feat: luarocks/rocks.nvim support

[mrcjkb]

Hey again 👋

This PR makes this plugin compatible with luarocks, and adds the luarocks-tag-release workflow, for automatically publishing tagged releases.

@Conni2461 I see this plugin doesn't have any semver tags.
Not sure if you are willing to start maintaining them (manually or automated)?
An alternative would be to just upload the scm rockspec (but that would take away the ability to pin installations).

I've tested this locally with the scm rockspec (luarocks make).

@Conni2461 do you have any interest in this?
Otherwise, I could move it to the NURR. But that would require patching the fzf_lib module.

I am interested, i can review this in 2 weeks

I am trying to install your plugin while using rocks, what is the installation path?

@Conni2461 any update on this? 😄
