Subject: [PATCH] Add a comment about version quotations to README

As described in the comment, due to a bug discussed on https://github.com/actions/runner/issues/849,
we currently have to use quotes for  '3.0' as a workaround.
This change makes it easy for people not to remove quotes as they misunderstand it's a typo.
