[feat(ci)]: Don't run all the CI (e.g. node tests) for documenation changes

**Describe the solution you'd like**

Node tests only run when relevant files change (e.g. CI files or src files)

all-contributors or other documenation-only PRs should not be required to wait on full test runs and happo diffs, etc

**Describe alternatives you've considered**

Leave it the way it is, but for small non-code PRs it introduces slower than desired feedback loop
