Hack around rebar3 compiling for version

What are we fixing? If you're with'ing "version-file": ".tool-versions" after you _use_ "actions/checkout", it's likely `rebar3` from `setup-beam` is compiling your project just to output its version This commit prevents that as per erlang/rebar3#2865 (comment)
