Offering a CLI tool to have better DX in feTS Client

[ardatan]

Instead of handling broken and invalid or huge (breaks TS Server and IDE)OpenAPI schemas in feTS Client typings
And many more things before getting feTS running;
We can offer a tool that

• Download the schema from a URL as YAML or whatever format and save it to the disk as JSON
• Validate the JSON Schemas
• Autofix them if possible just like @omnigraph/openapi does under the hood before converting it to GraphQL
