bump @babel/* packages (#35787)

Summary:
X-link: facebook/metro#987

While working on facebook/react-native#35786 I noticed some inconsistencies in the versioning for Babel and Flow across the monorepo. So in this PR I wanted to address that so that for 0.72 we'll have the codebase in a more consistent shape.

Happy to split in multiple PRs if needed.

## Changelog
[GENERAL] [CHANGED] - Bump Babel packages to ^7.20.0 (or closest latest release), bump flow parser to 0.206.0 in a few places that were left out from latest bump

Pull Request resolved: facebook/react-native#35787

Test Plan: CI is green.
