[TRI-1430] Improve the OpenAI integration documentation

[D-K-P]

Overview:

Update the OpenAI integration documentation so it is much easier to use as a reference.

We have just overhauled our GitHub documentation and would like all of the rest of our integrations to follow the same structure.

Please use the references and resources at the bottom of this post to complete this issue.

Pages to add:

OpenAI overview & authentication:

This page is currently this.

• Page Title: OpenAI overview & authentication
• Sidebar title: Overview & authentication
• Page content: authentication with OpenAI, in the same format as this. If there is no overview, write one. You can use their company website for inspiration.

OpenAI Tasks:

• Page title: OpenAI tasks
• Sidebar title: Tasks
• Page content: all the tasks available from our OpenAI integration, in the same format as this: https://trigger.dev/docs/integrations/apis/github-tasks. Please include code comments in all of the code examples. Also include one example at the bottom with clear comments. See references below for sample code.

References & resources:

• GitHub documentation to reference
• Our current OpenAI documentation in the GitHub repo.
• Example job code to use - job catalog and jobs showcase.
• We use Mintlify for our docs, documentation here

Important

Please include a video or screenshots of the pages when you submit a PR for us to check
