Dear Maintainer,

Please consider upgrading the luarocks package to version v3.10.0 or
later and relaxing the dependency on the lua5.x-dev packages.

Prior to this version, when attempting to install a "rock" (package) for
a particular Lua version without having the corresponding dev package
it fails with a message like:

$ luarocks install --lua-version=5.4 example.rock
when it consists of only Lua files.
