Support for alternative mod distribution platforms about moddermore

A few of these have been considered in the past.

• 9minecraft is known for illegal redistributing mods and other content without original authors' consent and is not trustworthy either, so it will not be supported.
• GitHub support was originally planned, but there is no unified format for game version and mod loader information. This would result in a quite painful user experience even if added.
• Custom file uploads is something I am thinking about, but the associated risks with malware, piracy and such are something I still have to consider.

Perhaps for GitHub I can make a dialog for the user to select a particular version and a particular release asset, but that will obviously take some time to develop 🤔

Quite interestingly, Thymine 1.18x version and some stuff in the "index" folder show up fully when I do it on Moddermore (could be a coincidence :/ but I'm pretty happy because I finished it before (actually during) Lunar New Year)
