This commit adds support for configuring a custom start timestamp
for Prometheus unit tests, allowing tests to use realistic timestamps
instead of starting at Unix epoch 0.

The return value of functions relating to the current time, e.g. time(),
is set by promtool to start at timestamp 0 at the start of a test's
evaluation.
This has the very nice consequence that tests can run reliably without
depending on when they are run.
It does, however, mean that tests will give out results that can be
unexpected by users.
If this behaviour is documented, then users will be empowered to write
tests for their rules that use time-dependent functions.

As a follow-up to #17344, add two configuration parameters for controlling label
name translation, both defaulting to on for backwards compatibility (currently
these behaviours are hardcoded as enabled):
* otlp.label_name_underscore_sanitization => Prefix label names starting with a
single underscore with key_ when translating OTel attribute names
* otlp.label_name_preserve_multiple_underscores => Keep multiple consecutive
underscores in label names when translating OTel attribute names

The detailed plan for this is laid out in
https://github.com/prometheus/prometheus/issues/16572 .
This commit adds a global and local scrape config option
`scrape_native_histograms`, which has to be set to true to ingest
native histograms.
To ease the transition, the feature flag is changed to simply set the
default of `scrape_native_histograms` to true.
Further implications:
- The default scrape protocols now depend on the
`scrape_native_histograms` setting.
- Everywhere else, histograms are now "on by default".
Documentation beyond the one for the feature flag and the scrape
config are deliberately left out. See
https://github.com/prometheus/prometheus/pull/17232 for that.

The last permutation of the translation options does underscore translation but does not add suffixes.
This translation option already exists in Mimir as otel_metric_suffixes_enabled, indicating external demand for this strategy.
There is an accompanying update to prometheus-docs to explain the use of this mode: https://github.com/prometheus/docs/pull/2688

Presumably, this will help with Loki alerts, but the added functionality is also generally useful.
For one, this enables `parseDuration` to also accept negative duration (as that's something that is also used in PromQL by now).
This also adds a function `now` to return the evaluation time of the template (as seconds since epoch AKA Unix time) and a function `toDuration` (akin to `toTime`), which creates a Go `time.Duration` from a duration in seconds.

Reverts #16730 and #16760
This is being done because we've noticed a problem in the spec that could
lead to name collisions if attributes name, version or schema_url are added
to the scope. They would collide with the already reserved labels
otel_scope_name, otel_scope_version and otel_scope_schema_url.
Since this new configuration option never made it into a release, we can
safely remove it from the 3.5 release. We'll sort this out for the 3.6 release

The new docs site will have syntax highlighting, so this adds language tags
to code boxes that are currently missing them. I didn't add `promql` as a
language yet since the highlighter doesn't support it yet, plus a lot of
the PromQL codeboxes in our docs aren't strictly valid PromQL, they are
more like multiple expressions listed in the same code box on multiple
lines. So I'm leaving that for sometime later.
In the HTTP API page, I moved the curl examples from the JSON codeboxes to
their own ones above the JSON output. I considered putting an "Output:"
text between the curl + JSON output, but I think the way it currently looks
without it is probably fine.
I also fixed a number of headings which were at the wrong level relative to
their nesting in the document.
I also removed `go` as a language from the Go template language examples,
because the Go template language isn't Go at all.
I also adjusted the indent on one codebox to be more reasonable (2 spaces
instead of 8).
And then finally, my editor made a bunch of whitespace changes
automatically, like removing trailing spaces.
