Need to "mint"/push datalad_crawler/version.py

[yarikoptic]

Followup to #86
In this repo (and many other "datalad-*" repos/extensions) we do not use versioneer (at least yet), and rely on having package/version.py (done in setup_support.py) provide that version which we change manually before release.

So release workflow (or somehow auto setup?) should be adjusted to update that file and include it in the ~/auto shipit

Without that - we still have outdated release on pypi and datalad_crawler package has old __version__.

After fixed here, I will implement/copy it in datalad-container with the same issue ATM.
