Misleading section "Example: Using an action inside a different private repository than the workflow" in "Workflow Syntax"

What article on docs.github.com is affected?

https://docs.github.com/en/actions/writing-workflows/workflow-syntax-for-github-actions#example-using-an-action-inside-a-different-private-repository-than-the-workflow

What part(s) of the article would you like to see updated?

The current example explains you must checkout the private repository and reference the action locally, which also necessitates setting up private access tokens as secrets.

However, after following Allowing access to components in an internal repository, the regular uses: {owner}/{repo}/{path}@{ref} seems to work just fine.
This is misleading and should be added as an example, or explained why this easier approach should not be used.
