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.
