improvement: repurpose graphql-language-service for LSP DX (#1535)

- `graphql-language-service` moves to `graphql-language-service-cli`
- `graphql-languageservice` becomes `graphql-language-service` because NPM thinks the former is too alike
- update packages to use new `graphql-language-service`
- bump major version
- update documentation to reflect these changes
- add bin placeholder to `graphql-language-service` to stderr out to users the new package to install
