nvim: Automatically install linters and formatters

Switch out mason-tool-installer for mason-conform.nvim and
mason-nvim-lint as respective wrappers for automatically installing
formatters and linters.

Follows the same principle as mason-lspconfig.nvim (in fact, the repos
are mostly based on the same code) and apply the concept to the other
tools: Whatever is enabled in the respective plugins (lspconfig,
nvim-lint and conform.nvim) will automatically be installed by mason.

This is really neat and basically takes care of me ever having to
interact much with Mason itself or manually set up the tools to be
installed. All I have to make sure is that they're updated once in a
while.
