check command failed if schema is not available

[oceandrama]

Describe the bug

It looks like check command should only validate queries with existing introspection (and it works exactly like this), but before that it also checks for schema availability, which may not be possible, for example, in ci/cd without internet access. I think this is unneccesary step, which may be skipped

The check command is able to output any diagnostics that the GraphQLSP plugin outputs in your editor/IDE. As such, it needs the schema and operates on schema-based validation rules as well.

If your schema isn't permanently available (for example if it's built up and/or stored in a different repo) you may want to consider downloading it and committing it to your repo: https://gql-tada.0no.co/get-started/workflows#downloading-schemas
