Support for alternative mod distribution platforms

[EldraTheThird]

Mods other than CurseForge/Modrinth (like Thymine Mod, etc) are not added when creating modpack

To test it, I tried creating a modpack on Prism Launcher

1. First add Thymine and mods not available on Modrinth/CurseForge
2. Export it to a .zip file and select MultiMC/Prism instance
3. Select the exported zip file, name it and click Submit. And you will see some mods not fully displayed

Moddermore's mods list showing

And here is the list of mods included in Prism Launcher

You can be pretty clear that Thymine is still visible in Prism, but not in Moddermore :/

Desktop

• OS: Windows 10 Home SL
• Browser: CocCoc 114.0.140 64bit
• Version: 114.0.140 64bit

I think it is advisable to add scanning for mods from other sources, this will diversify the number of mods in the modpack
And I really like Moddermore :D Because it helps me make modpack much faster than ATLauncher (and more convenient when this is a website)

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.

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)

I would love this. As of right now I have to put the GitHub link in the list description or do something else off-site.
