Create a branch to support major wildcard version

[LitoMore]

Problem

Our raycast/extensions is using raycast/github-actions/setup-git@master and raycast/github-actions/git-commit@master. But in raycast/github-actions, the raycast/github-actions/git-commit is using the raycast/github-actions/setup-git@v1.16.0. Which is not consistent.

Solution

See https://github.com/actions/toolkit/blob/main/docs/action-versioning.md.

The solution in the official documentation is to use a v1 tag to manage the major version. But it requires you update the tag with --force on every update.

A better solution is to use a branch called v1 and keep our code in this branch.

Benefits

We don't need to update all versions for raycast/extensions and raycast/github-actions on every update. And it's easier to keep your usages both in raycast/extensions and raycast/github-actions consistent.
