refactor(nvim): remove nvim-lspinstall

Remove the kabouzeid/nvim-lspinstall plugin and configure the language
servers in init.lua.

I don't use all of the languages bundled with nvim-lspinstall, and the
ones that I use are already installed via Ansible in my
ubuntu-provisioning repository.

Fixes #20
