fix(FormGroupLabel): enable screenreaders to read a label's "optional" text

[LinKCoding]

Overview

Currently, Gamut's forms' labels include either * to signify required, or (optional) to tell learners what fields are necessary.
Both are set to aria-hidden but a test.io filing requests that the (optional) be read aloud.

This PR changes the (optional) text to be read along with the label text and keeps the aria-hidden on the *.

PR Checklist

• Related to JIRA ticket: GM-910

3. Turn on VO and check that the optional text is being read aloud
4. NOTE: you might need "control" + "option" + arrow key to access the text since it's a non-interactive item
5. Optionally, but appreciated (6 + 7):

If we're reading (optional) i think we should also read (required)

If we're reading (optional) i think we should also read (required)

That's a good point Tim, was there a field that you noticed VO didn't announce "required"?
We have it so that the asterisk (*) isn't announced but fields that are required have an aria-required=true

So VO should pick that up.

But with this PR, we also had selectively decided to NOT have VO announce the "optional" text since it seemed implied that anything that didn't announce "required" must be optional. However, there seems to have been a change in guidance, so also changing it to have VO announce "optional" text for labels.

Setting aria-required=false also doesn't do anything, i.e. the VO won't say "optional".

Preview is being funky but confirmed everything is working as expected locally and on the mono and monolith previews
