[ENHANCEMENT] Support for the different versions that Essential supports.

[KTrain5169]

Our site is heavily based around Essential alternatives for modern versions of Minecraft. As such, people on older versions can't use our site much. I think adding this feature can help these people.

Checklist:

• Site change: Add options (maybe through buttons) on /alternatives that allows the user to switch between the different version of Minecraft that Essential supports.
• Site change: Add a special section (maybe represented by images?) that denote what loader the mod works for and what versions of Minecraft does that mod support on that loader.
• Crowdin: Update with new strings

This seems like a lot of work to do with how many versions Essential supports. It would make more sense if @intergrav got around to making Vital versions for them, based off of our list

We don't have to actually implement a button and slider system for this or whatever, it can just be new notes for what version and corresponding loader the mod supports

It can be that simple, but it'd honestly make a lot of difference
