Allowing "!=" as alias for "~="

[ToldFable]

Seeing as there are already C-like operators (ex: a += 1 as an alias for a = a + 1), it would be visually pleasing to also allow != as an alias for ~=.

Also, it would help psudo-code-ness as ~= usually means "about equal to" in most other contexts.

Note: if this feature is added, the majority of people probably won't care/notice, but some might get mad

I meant to write an RFC, not a discussion, but I'd be glad to have a discussion on this topic if anyone's interested.

I'm kinda new to RFCs haha, I should've done more reading (though it's arguably esoteric to be expected to read CONTRIBUTING.md when I just want to suggest something, it might help to include a link to it in README.md)

Let me open an issue to discuss this before making any pull requests...
#855

We considered this in the past. Fundamentally what we decided is that having two different syntax options for a single construct adds less value than it adds confusion. Luau also doesn't have unary ! (and probably shouldn't!), so it would be slightly odd to have != without ! although Python does the same.
