ci(commit-check): Upgrade commit-check GitHub action to v2

Conventional Commit branch rules permit branches of 'fix/' and 'feat/'
which are short for 'bugfix/' (or 'hotfix/') and 'feature/'
respectively: https://conventional-branch.github.io/#branch-naming-prefixes

commit-check-action v2 introduced commit-check.toml which defaults to
permitting these abbreviated branch names:
commit-check/commit-check-action#152
