Conditionally show toggle for null-ls

[Steven--]

A toggle for null-ls is shown even if null-ls is not installed.

This seems to be hardcoded line 22 of lsp.lua.

Would it be possible to only show such an option if null-ls is actually available? Thanks!

I second this. I don't use null so it's a bit weird it shows up by default, esp if the lsp isn't loaded
