ci: Update on_master workflow conditions (#809)

## Summary
- Pre-release runs only for `feat`, `fix`, `perf`, `refactor`, `style`
conventional commits (skip all others)
- Doc release runs only for `docs` conventional commits (skip all
others)
- Tests skip only for `docs` conventional commits
- `startsWith(github.repository, 'apify/')` is not necessary since it is
only the `on_master` trigger.
