Looks clean to me, @MackinnonBuck. I presume you're seeking some feedback from folks with Aspire expertise; beyond that, what input/feedback/testing would be helpful for you on this?

Thanks @jeffhandley - If others are interesting in trying out the new Aspire + Azure OpenAI + Azure AI search template, that would be helpful to validate that I didn't miss any steps in the README. But I would say additional testing isn't a hard requirement before the PR merges; I was able to manually validate the changes myself 🙂

cc @eerhardt, @JamesNK, @davidfowl - I would appreciate getting some eyes on the Aspire-related changes 🙂

Update to 9.4

[jeffhandley]

Bumping to 9.4 makes sense before merge, but otherwise this looks great, @MackinnonBuck.

@sebastienros can you review this ?
