Problem:
If `neovim` module is not installed, python and ruby healthchecks fail:
- ERROR Failed to run healthcheck for "provider.python" plugin. Exception:
.../runtime/lua/provider/python/health.lua:348: attempt to concatenate local 'pyname' (a nil value)
- ERROR Failed to run healthcheck for "provider.ruby" plugin. Exception:
.../runtime/lua/provider/ruby/health.lua:25: attempt to index local 'host' (a nil value)
Solution:
Check for non-nil.
