fix: badge workflow commits directly instead of creating PRs (#121)

* fix: badge workflow commits directly instead of creating PRs

Replace peter-evans/create-pull-request with direct git push.
Removes need for pull-requests:write permission and the repo setting
'Allow GitHub Actions to create pull requests'.

Uses [skip ci] in commit message to avoid triggering itself.

* chore: trigger CI
