nvim: Fix zk plugin and lsp loading correctly

The plugin was not loading since lazyloading was not given an event
to start it with. Now, anytime any zk command is given, or we enter
a prose-like filetype the plugin is sourced.

The zk lsp on the other hand was started twice whenever the plugin
was loaded, since we also loaded it through the lspconfig manually.

This commit fixes both issues by sourcing and plugin and letting the
plugin load the lsp as well.
