[Security solution] Rename Generative AI connector to OpenAI

[stephmilovic]

Summary

Follow up from #166662

Resolves items 1 and 2 of issue #166960

1. Renames Generative AI connector to OpenAI (keeps .gen-ai id so no migration needed)
2. Renames GeneralConnectorFeatureId to GenerativeAIConnectorFeatureId

I tried to leave o11y code alone besides file path changes and a few translations related directly to the connector name. @dgieselaar could you please take a look and let me know if I should do more or less?

@lcawl Could you please help me figure out how to fix this error ...

I've created a temporary "redirect" page in this PR and then we can fix the broken links in the Observability and Security docs via elastic/observability-docs#3251 and elastic/security-docs#4000
