Skip editable dependencies as they are no longer supported as we write them

The bump of requirements-parser to 0.5.0 broke the support for editable dependency as we usually specify them (i.e. -e path/to/package).

The local regex used by the package is no longer matched. The job of this bump-bot was never to check the content of all the lines in the requirements files, but simply bump non-editable dependencies. That's why I did filtered editable dependencies out first (to avoid parsing them at all).
