feat(toMatchAriaSnapshot): add raw saving option

[vincenzo-gasparo]

Add exact parameter to toMatchAriaSnapshot to save raw data

Fixes #38074, references #38074.

Thank you for your contribution. We always ask that people file issues first so we can triage and decide whether or not a PR is warranted, but in this case we do think this is something worth implementing (and it's a trivial implementation).

Minor comments: just naming and supporting both overloads.

@agg23 I cannot manage to make this code to work:

[`property: TestConfig.updateSnapshots`]

It gives me this error:

Error: Undefined member reference: [`property: TestConfig.updateSnapshots`]

Can you give me some help?

@vincenzo-gasparo this is because TestConfig is a JavaScript only concept; the other language ports do not support it (no test runner). You should disable the docs for this new flag in the non-JS platforms by setting langs: js everywhere, including on the new update parameter.

@agg23 , even using langs: js for the new update parameter in toMatchAriaSnapshot, the build still fails with
"Undefined member reference: [property: TestConfig.updateSnapshots]"

I tried to add

### option: LocatorAssertions.toMatchAriaSnapshot#2.update = %%-js-assertions-aria-snapshot-update-%%
* langs: js

in class-locatorassertions.md

and

## js-assertions-aria-snapshot-update
* langs: js
* since: v1.57
- `update` <["raw"]|["relaxed"]>

Defines how snapshots are written when used with [`property: TestConfig.updateSnapshots`]. Defaults to `'relaxed'`.
* `'relaxed'` - Writes an ARIA snapshot that uses flexible patterns (for example, regular expressions for numbers) to reduce flakiness from minor changes.
* `'raw'` - Writes the exact ARIA snapshot without transformations. This is strict and will fail if values change.

in params.md

but still does not work

Ok, thank you for trying to get the docs to work. I think what you have here is fine. Just need to restrict it to JS.
