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

step() is a new keyword introduced to represent the query step width in duration expressions.
min(a,b) and max(a,b) return the min and max from two duration expressions.

* fix(promql): histogram_quantile NaN observed in native histogram
Fixes: #16578
See the issue for detailed explanation.
When a histogram had only NaN observations and no normal observations,
we returned 0 from the quantile, which is completely wrong. If there were
normal observations but we went over them, we returned the upper bound of
the existing buckets, however that contradicts expectations on
histogram_fraction. Now we return NaN if the quantile is calculated to be
over all normal observations, falling into NaNs (in a virtual +Inf bucket).
We also return info level annotations if we see any NaN observations.
The annotation calls out if we returned NaN or even if we took the
virtual +Inf bucket into account.

* fix(promql): histogram_fraction NaN observed in native histogram
Fixes: #16580
According to the specification we should not take NaN observations
into account when calculating the fraction. This commit fixes that
and adds an info level annotation to let the user know about this.

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.
