Is your feature request related to a problem? Please describe.

I'm developing a neovim plugin that requires a C component built using LuaRocks. The build process depends on environment variables to locate third-party libraries. Standard LuaRocks allows passing parameters or setting environment variables during the build using the spec file. However, lazy.nvim's current integration with LuaRocks doesn't provide a way to pass these necessary parameters. This limitation prevents the correct compilation of plugins with external C dependencies.

This feature request proposes adding support for passing parameters (e.g., environment variables, build flags) to the LuaRocks spec when building plugins with lazy.nvim. This would bring its LuaRocks integration closer to standard LuaRocks functionality and enable building more complex plugins.

Describe the solution you'd like

This feature request proposes adding an extra_arguments table to the build configuration. This table would contain arguments that are passed directly to the luarocks install command. This would allow users to customize the build process as needed.

return {
  "xxxxx/my-plugin",
  build = { "rockspec", extra_arguments = { "LIBFOO=/opt/foo", "DEBUG=1" }}, -- Multiple arguments
}

This should result in lazy.nvim executing:

luarocks install <internal-arguments> my-plugin LIBFOO=/opt/foo DEBUG=1

This feature would significantly enhance the flexibility of building plugins with external dependencies using LuaRocks within lazy.nvim.
