Remove missing labels from Dependabot

Prevent this: #48 (comment)

Labels

The following labels could not be found: skip issue, skip news. Please create them before Dependabot can add them to a pull request.

Please fix the above issues or remove invalid values from dependabot.yml.

Or shall we add a dependencies here and in https://github.com/python/library-fuzzers/labels ?

I don't really see any need for a new label, we don't have a sea of PRs to sort through in this repo.
