GitLab plugin fails to start: TypeError: 'ABCMeta' object is not subscriptable

Hi there,

probably since upgrading to maubot 0.2.0 the GitLab plugin (v0.1.1) fails to start with the following error:

TypeError: 'ABCMeta' object is not subscriptable

Any ideas?

Environment:

Docker
maubot 0.2.0
GitLab CE 14.4.2

Thanks,
Thilo

This was fixed in 7e853e5

Excellent, thanks a lot! I can confirm that the v0.2.0 plugin works like a charm!
