Installation instructions in README does not work

[pieterbreed]

This instruction in current README.md

# Reference a semver major version only (GitHub recommended)
- uses: asdf-vm/actions/install@v4

When I try this, I get the following error:

Error: Unable to resolve action `asdf-vm/actions@v4`, unable to find version `v4`

I checked, there is no v4 tag in the repo, maybe this is the issue.
