Add LUA support #3971
Description
Is your feature request related to a problem? Please describe.
The LUA projects are not benefitting from this project
Describe the solution you'd like
In the LUA ecosystem there are 2 linters (at least this are the ones I know), luacheck (which hasn't been updated since 6 years ago) and selene (currently updating), and 1 formatter, stylua.
Note
The listed ones, are those which are popular and widely used.
In my personal opinion, I think that selene is better because, apart from being currently maintained, it has a more human-like way of configuring and displaying the errors than luacheck.
Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Additional context
I have made a selene linter action and there is one for stylua.
