Is there a way to install additional packages, besides the base LSP

[hahuang65]

For example, for Ruby, solargraph can be installed, but it also can be augmented with some gems, like solargraph-rails, rubocop, rubocop-rails, rubocop-performance...

Is there anyway to install these without going to ~/.local/share/nvim/mason/packages/ and installing by hand?

Hey! Unfortunately not yet, see #392 for umbrella issue.
