Lua 5.2 should be re-added

[thesoftwarephilosopher]

I don't know when it was removed, but many Mjolnir users depend on Lua 5.2 being installable by a third party app (brew or macports). It's understandable that Lua 5.3 should be the default lua formula since it's the latest version, but it would be helpful to several of our users if Lua 5.2 were re-added as lua@5.2 or something. Considering Lua 5.1 is still there (as lua@5.1) it seems like this isn't too far out there of a request.

Please see the guidelines for versioned formulae. Upstream has indicated that there will be no further releases for 5.2 so we will not be adding it to Homebrew/homebrew-core. You'll need to update your software to support 5.3 or maintain 5.2 in your own tap.

@ilovezfs fwiw Lua consumers tend to be very conservative about updating (likely why 5.1 is still present, since many users have no intention of moving to a more recent version, plus it's the only version directly comparable to LuaJIT, which has stated previously that it will not support some of the newer features in 5.2/5.3) so this may not necessarily be the most helpful interpretation of the guidelines.
