lsp: npm registry completions on module specifiers

[dsherret]

The LSP should support npm registry completions on module specifiers.

It seems the endpoint to use is: https://github.com/npm/registry/blob/master/docs/REGISTRY-API.md#get-v1search

We'll definitely need to set boost-exact:false as there are so many typo packages. For example: https://registry.npmjs.org/-/v1/search?text=react-nati%20boost-exact:false&size=5

I believe the change would occur in this function and work similarly to how deno.land/x completions do: https://github.com/denoland/deno/blob/main/cli/lsp/completions.rs#L137
