fix: Ensure field ARIA labels are correct for invalid values (experimental)

[BenHenning]

The basics

• I validated my changes

The details

Resolves

Fixes #9466

Proposed Changes

Ensures FieldInput's ARIA labels are recomputed when an invalid value is attempted to be set.

Reason for Changes

Previously the FieldInput would continuously update its ARIA label as the value changed, including for invalid values. If the editor was cancelled this would correctly revert but if an invalid value was attempted to be saved then it would cancel the update but not correct the ARIA label.

Test Coverage

No new tests are needed for this experimental change. This has been manually verified locally using FieldNumber in Core's advanced playground.

Documentation

No documentation changes are needed for this experimental change.

Additional Information

None.

LGTM once you fix that commit lint issue.

This is a very odd failure that's completely unrelated to the PR and the branch:

It's also consistently failing.

[BenHenning]

Okay it's failing for the other checks. This is a change in GitHub's ubuntu-latest that isn't playing well with NPM. So much for hermeticity in package management. :( This probably means develop is broken, too.

[BenHenning]

Filed #9475 to track.

[BenHenning]

Yay looks like CI is behaving like normal again (with the expected failure). PTAL when convenient @rachel-fenichel.

Thanks for the quick reviews!
