docs: address PR review — merge duplicate link, expand RSC label

- migrating-from-react-rails.md: combine two consecutive sentences pointing to example-migrations.md and clarify that in-progress PRs live in meta issue #3125, not on the example-migrations page.
- example-migrations.md: expand the terse "RSC" link label to "React Server Components (RSC)" for consistency with sibling entries.
