nvim: Remove harper lsp

For the time being remove harper (code spellcheck) lsp from the
automatically loaded LSPs. It's not *bad* per se but also requires way
more setup for me to be useful and throws up false positives all over
the place. Worst of all though it does not seem to actually stop
producing diagnostics when it is stopped (with `LspStop <harper-id>`)
like all the other LSPs do, so there is no way to get rid of its
results.
