* Correctly generate rulesLintConfig when --lint=none is set (#17399)
If I run promtool check config --lint=none I get:
```
Checking rules.yml
FAILED:
rules.yml: unset nameValidationScheme
```
This is because passing --lint=none stops newConfigLintConfig from generating rulesLintConfig which is needed for validation.
It means that defaults are used then, one of which is unset value for metric name validation, causing this error.
Fix this by handling --lint=none case correctly and still generating rulesLintConfig.

This reverts commit 93887a9b82a71613067ff0706248c18fe131c5b0.
See discussion at https://github.com/prometheus/prometheus/pull/17240 - I had
thought this was a simple and clear bugfix, but multiple people were depending
on the previous behavior already, and we want to err on the side of stability.

The modifiers were already printed as part of the VectorSelector, so for:
`foo[5m] anchored`
...the output was:
`foo anchored[5m] anchored`
Similar to how it was already done for `@` and `offset`, I now removed these
modifiers in the copy of the vector selector that is used to print the matrix
selector. I also removed some unused code that restored the copy of the vector
selector after overwriting its fields. AFAICS there was no use in doing that,
since it was a copy already that would just be thrown away after printing, and
the original selector wasn't affected. I also removed an erroneous comment in
`atOffset()` where no actual copying took place and no fields were overwritten.

Fixes#17370
In Prometheus v3.7.0, using labelmap actions with replacement patterns
containing regex variables (e.g., `$1`, `${1}`) would fail validation
when `metric_name_validation_scheme` was set to `legacy`, causing
Prometheus to fail at startup with:
"$1" is invalid 'replacement' for labelmap action
This was a regression as the same configuration worked in v3.6.0.
The issue was in the validation logic: while UTF-8 validation correctly
allowed `$` characters, legacy validation incorrectly used
`IsValidLabelName` which rejects `$` characters. The fix ensures legacy
validation uses `relabelTargetLegacy` regex which explicitly supports
regex template variables.
Added test cases to verify labelmap validation works with both `$1` and
`${1}` replacement patterns under legacy validation scheme.

Add ANCHORED and SMOOTHED keywords to the maybe_label and
metric_identifier rules in the parser grammar, allowing them
to be used as metric names and label names, similar to other
keywords like 'offset', 'step', and 'bool'.
This fixes an issue where expressions like `anchored{job="test"}`
and `sum by (smoothed) (some_metric)` would fail to parse.

Loading the local region from the Instance MetaData Service broke in v3.7. This adds the IMDS call back in order to load the local region when no other method has set the region.

After the upgrade to AWS SDK v2, the EC2 and Lightsail service discovery
stopped working when using the default AWS credential chain (environment
variables, IAM roles, EC2 instance metadata, etc.).
The issue was that the code unconditionally created a StaticCredentialsProvider
with empty credentials when access_key and secret_key were not configured. In
AWS SDK v2, this causes a "static credentials are empty" error and prevents
the SDK from falling back to its default credential chain.

The upgrade to prometheus/otlptranslator@7f02967de0 fixes two label
name translation bugs, when in legacy name translation mode:
* 'key' is no longer prefixed when label names start with an underscore
* Multiple consecutive underscores are combined into one
