Add Mangane as optional UI : setup config panel

[lapineige]

Based on this topic, it seems that installing Mangane, an alternative Pleroma and Akkoma frontend, could be automated in a rather simple way and maybe integrated in the config panel.

What do you think about that ?

That topic provide a list of step to install it manually on Yunohost, I believe it would be rather "simple" to transfer it to a config panel…

Anyone willing to try ? 🙂
