Fixes #952

What is the current behavior?

Issue Number: #952

requirement("dependency") didn't work if the dependency had any number of hyphens in its name (for example requirement("google-cloud-storage") did not work in a BUILD.bazel file.

The error encountered was, for example:

bazel:106:6: no such package '@[unknown repo 'pip_typing-extensions' requested from 
@rules_python~0.16.1~pip~pip]//': The repository '@[unknown repo 'pip_python-dateutil' requested from 
@rules_python~0.16.1~pip~pip]' could not be resolved: No repository visible 
as '@pip_python-dateutil' from repository '@rules_python~0.16.1~pip~pip' and referenced by 
'@rules_python~0.16.1~pip~pip//:python_dateutil_pkg'

What is the new behavior?

requirement("dependency") now works with hyphens in the name.
