Quilt builds currently aren't shipped, and instead Quilt users have to use the Fabric downloads. Let's get dedicated Quilt builds!

Going to be scrapping this from 1.4 for a few reasons:

• We already depend on Architectury API and Forge Config API Port, which both don't have Quilt builds anyways.
• 1.4 is coming out much later than I want it to be, so I'd rather focus on things that make major end-user changes
• I take very little advantage of the Fabric API that Quilt has to duplicate to my knowledge (don't know how much Architectury and Forge Config API Port utilize it), so I don't see any breakage with Quilt folks happening anytime soon,*

That said, this is absolutely not off the table, and I very much want to see this issue through. Just that now isn't an ideal time for it.

*: If breakage does happen though, it'll be top priority to fix; Quilt users should be able to use ImmersiveMC. Just that making standalone Quilt builds isn't the highest priority since Fabric builds can be used while I get Quilt builds going.

I don't think anyone uses quilt 💀, and if they do, the fabric version should work fine, right?

The Fabric version works fine (hence why this is a lower priority issue (see the comment above yours)). However, having a Quilt-specific build would be nice for people who use Quilt and for if/when Quilt breaks off from supporting Fabric compatibility on top of their own.

Makes sense, just don't stress too much about it.

From the work in #307, I left Forge Config API Port as a requirement in quilt.mod.json. That should be removed when this issue is tackled.
