Biome fixes migrate comma bug

A malformed trailing comma could break strict JSON migrations when the renamed rule was last in its group; this patch fixes it and adds coverage.

Fix malformed migrate output for renamed rules (tom-groves5f837df)

biome migrate now preserves separator state correctly when a renamed rule is the last item in a group, preventing an invalid trailing comma from being emitted. That matters because the bad output could abort migrations of strict-JSON biome.json files with a parse error.

Other misc changes

  • Added a regression test and snapshot for renamedRuleLastInGroup.
  • Changelog entry for the patch release.
