Hyperkitty depends on robot-detection which has been archived

In https://gitlab.com/mailman/hyperkitty/-/blob/8e88bda5a0d761f09c355f1443d3db2fad6feef2/hyperkitty/views/thread.py#L40 hyperkitty imports robot-detection, which is archived and has last seen a release 8 years ago.

In #14 (comment 832747481) it is claimed that hyperkitty no longer depends on robot-detection (but even its pyproject.toml still states it as dependency).

I think this dependency should be removed.
