fix(repo): update stale ChatTwo paths in repo configs

- .gitattributes: linguist-generated path was still pointing at the
  pre-v1.0.0 ChatTwo/Resources/ tree, which silently let the renamed
  HellionChat/Resources/Language.*.resx files leak into Linguist's
  language statistics
- bug_report.yml: drop the "or ChatTwo" filter hint; the plugin only
  emits HellionChat.* into /xllog since the v1.0.0 standalone cut
