[ci] Remove archival for lint patches (#8745)

When downloading a patch to fix linting errors, it's annoying to have to
unzip it, particularly when it's a single file. This PR updates the
`upload-artifact` action to v7, which allows for uploading an artifact
without zipping it. It also sets archive to false for all patches
generated by linting.
