…ility The PR bumps apply-setters to v0.2.4 in go.mod. Adding v0.2.4 to the functions registry is required so Kptfiles referencing the new version work with the built-in runner. v0.2.0 is kept for backward compatibility with existing Kptfiles that already reference that version. Also revert testdata Kptfiles back to v0.2.0 since both versions are now supported by the functions map.

This PR contains code changes as well as documentation changes. The title and descriptions says the PR only contains documentation changes.

I have a feeling that you did a rebase instead of a merge what pulled lots of non related content to this PR.

I would suggest maybe to start fresh from a branch created from the actual upstream main branch.

Related to the content of the PR. Do we already know what are the breaking changes in v1.0.0?
