Changesets: Bump form package to test release process (#2410)

## Summary:

This PR is meant to bump the version of the form package to test changesets.

We are seeing if a change being applied in #2409 will fix the issue we are
seeing with changesets not being triggering PR checks at all.

This is causing that packages are not being published to NPM.

Issue: XXX-XXXX

## Test plan:

Land this PR and see if the changesets checks are triggered once the Release PR
is created.
