PyPI packages with underscores cannot be downloaded

[ezekg]

Looks like PyPI automatically dasherizes package names, e.g. for a package foo_bar, PyPI actually makes a request for foo-bar, which doesn't exist, resulting in a 307 redirect to pypi.org. Need to look at the spec again to see how this should be handled.

For packages for the pypi engine, we could normalize the package key per the spec:

class ReleasePackage
  normalizes :key, with: -> key { key.gsub(/[-_.]+/, '-') }, if: :pypi?

  def pypi? = release_engine.key == 'pypi'
end

See: https://peps.python.org/pep-0503/#normalized-names

Workaround is to update the package's name to be dasherized, e.g. change foo_bar to foo-bar.
