chore(skills): Add bump-size-limit skill

[Lms24]

As a "manual but less manual than editing .size-limit.js" alternative to #19690, this PR adds a skill that takes care of bumping size limits. I also added a test:size-limit script for convenience since we didn't document elsewhere how to manually run the size-limit CLI.
