Update ERB handling

[akerl]

This resolves the deprecation warnings I'm seeing with puppet-syntax:

It looks like this is still using Travis CI and not GitHub Actions. I'm first going to send a PR to convert it so we have CI to confirm whether it works or not.

#130 is failing for some reason, but I don't know why.

[akerl]

Any chance of merging this prior to the GH Actions change, if that’s a deeper rabbit hole?

[smortex]

@akerl can you please rebase this on top of #130?

From your local repository, on the patch-1 branch:

git remote add ekohl git@github.com:ekohl/puppet-syntax.git
git fetch ekohl
git rebase ekohl/gha
git push -f

[ekohl]

I've included the patch in #130 now, let's see what that brings.

Obsoleted by #130 where I included this with an additional fix for Ruby < 2.6. Thanks for pointing this out!
