Ensure that core mods tab is visible on correct versions

[Trial97]

fixes the described behavior from #2017 where the core mods tab is visible on the latest forge versions

[TheKodeToad]

wouldn't it be better to update the tab when Forge is downloaded than to do this?

[Trial97]

The tab will be visible until you start the game.
Right now if you open the edit window that tab is visible(for new instances that do not have the version yet loaded).And is only visible on first view(if you close the window and open it again that tab is no longer there)
So if we do this when forge is downloaded then it would be already too late.

Forge's JSON file should automatically be downloaded 🤔

[Trial97]

Not really, it downloads but because it's async it is not instant resulting:

• you open the window
• if the file is not there download it
• because we do not for it to download we display the core mods tab
  PS. Feel free to test it yourself(with and without my fix)

This will cause a freeze which is worse than a delay. Please try an alternative like the one I suggested.

**Not a freeze, still quite weird behaviour though imo

Fixed following you suggestion TheKobeToad
