Amend example usage to specify the Lua implementation flavor

Note: it'd be simpler if the lib artifact was named "lua" instead of "luau" like it is now.

I hadn't considered the library artifact name causing issues. I do think it is reasonable to rename it to "lua".

Note that there actually are docs for how to specify the version. See the build documentation of docs.md here: https://github.com/natecraddock/ziglua/blob/main/docs.md#build-documentation

But your PR does suggest that the documentation could be clearer, or maybe everything in docs.md could be moved to the readme? I'm not sure yet.

I can send a PR if you don't get to changing it first. I think it's better renamed so that the usage instructions are simpler.

I had completely missed these docs! (not the first time) I would be in favor of merging them with the main README.md. The links to API references could be kept, but maybe retitle to "Ziglua API reference [Lua 5.1]" or something similar?

Have a nice computer-less few days. :) I have everything running on my side, I'm just reporting what I find when things are fresh in my mind.

With #43 merged, I don't believe anything in this PR is needed anymore.

The library is still named "luau" internally, but with the new modules api, there isn't a need to use ziglua.artifact("...") anymore. It is now linked to the module.

I also updated the readme. If you think the docs could be improved, or "luau" should be renamed to "lua" again, just let me know!

Really cool stuff - I like these improvements (both in Ziglua and in Zig itself)! I read through the README and selecting Lua flavor is very clear now.
