At a high-level, these items as described seem valid for RC3 but I'll defer to @desrosj @dream-encode @getsource and others on the release team for any technical concerns with the changes themselves

I realize it's quite a large number of PRs again this time -- more than for RC 2 😕

FWIW, 5 of them add block deprecations that were previously missed:

• Table Block: Add a deprecation for the figcaption element class name gutenberg#45161
• File Block: Add a deprecation for the button element class name gutenberg#45159
• Video: Add a deprecation for the caption element gutenberg#45169
• Embed: Add deprecation for the caption element gutenberg#45166
• Gallery: Add a deprecation for captions in the gallery block gutenberg#45173

Their absence would cause blocks saved in 6.0 to break in 6.1. Here's the relevant issue: WordPress/gutenberg#45153

WordPress/gutenberg#45087 only affects e2e tests in the GB repo -- it doesn't have any impact on code in Core. (It does touch code in the packages/e2e-test-utils-playwright folder, but that package is marked as private and hasn't been published to npm yet.)

It was needed on GB's wp/6.1 branch for e2e tests to pass after WordPress/gutenberg#45074 was merged.

WordPress/gutenberg#45265 only affect's GB's "compatibility layer" with WP 6.0. That PR was needed for GB's own PHP unit tests to pass after I landed r54670.

It also doesn't have any consequences for Core: The corresponding code in Core was previously updated.

Closing in favor of #3527.
