Diagnostics page does not show Submodules version

[amuehlem]

servers/serverSettings/diagnostics tries to get the status of the submodules via git, current RPM does not contain git as dependency and any git related information. Therefore the version cannot be shown.

I will open an issue on the MISP side to consider that case.
