Updated the homepage to what seemed more suitable (their official homepage) and added the license in the formula as well (2 different commits). (Inspiration: #58225)

Thanks for the PR, @urwrstkn8mare!

This looks correct to me. The style issue seems to be a bug. I'm looking into it

[Rylan12]

Okay, I've created a fix in Homebrew/brew#8862. Once that's merged this will be good to go!

[Rylan12]

The fix has been merged, but you'll need to rebase your branch onto the latest master to fix the new issue.

@Rylan12 do I need to fix the issue to merge? If so, is there any easy way to rebase my branch onto the latest master.

[Rylan12]

The issue was unrelated to this PR, so this should be good to go once CI runs (I went ahead and rebased for you).

You can use the git rebase and git push --force commands to do this in the future (there's a brief explanation here)

[urwrstkn8mare]

Thanks a lot for that. I'll make sure to have a look so in the future I'm able to do it myself. :)

[Rylan12]

Thanks again, @urwrstkn8mare!
