Updated the title after looking at the commits since 564.5 in openapi generator -

• f3411ce - Add ability to pass language target for validation (#2470) (commit by @kanwardeep007)
• 292aa49 - java - simplify client credentials hook, oauth2-password multi-option support preparation GEN-1261 (#2465) (commit by @davidmoten)

This changes in this PR is linked to https://github.com/speakeasy-api/openapi-generation/pull/2470

New Logic
We now pass the target language information from the speakeasy cli command when possible and use it to validate the openapi document. The validation step contains actual validation of the openapi doc and generating the SDK with the target language to see if there are any errors

Before this PR
If we run speakeasy quickstart for a client openapi spec which contains jsonl or x-ndjson response we get the following output

After this PR

The lint error in CICD comes because the openapi-generation version hasn't been updated which contains the new arguments. I want to make sure people are happy with this PR before I merge changes in the openapi-generation (openapi generation pr here)

Otherwise looks good to me
