Version carries .2 suffix

[homeworkprod]

The current version, according to the release in the GitHub project, is 0.8.2. The version on PyPI for this release (also shown in the footer of the web UI), however, is v0.8.2.2.

The project contains to versions – in version.json and in rq_dashboard/version.py – which differ, and the latter having a .2 suffix.

For example, see the most recent version bump in e1a90e8.

Please align the values so that intended(?) and actually published (to PyPI) versions match.

I'd make a PR, but that would interfere with the process/automation and/or result in lowering the version number unintentionally.
