Fix sherlock workflow again (#5788)

**What's the problem this PR addresses?**
<!-- Describe the rationale of your PR. -->
<!-- Link all issues that it closes. (Closes/Resolves #xxxx.) -->

After upgrading alpine for the sherlock workflow in #5718, the workflow
still fails due to newer versions of alpine no longer having the
`python2` package.

Fixes #5709

**How did you fix it?**
<!-- A detailed description of your implementation. -->

Since we removed the old website in #5742, berry no longer depends on
`sharp` so I just removed all the alpine packages needed to build
`sharp` including `python2`
