[Feature request]: Plan for aspnet 11 support / OpenAPI 3.2.0 support

[baywet]

Is your feature request related to a specific problem? Or an existing feature?

We just merged the upgrade to OpenAPI 3.2.0 in asp.net 11, the plan is for this to go out with preview2. The default emitted version is still 3.1 for now to give the ecosystem time to try the preview, and upgrade the chain of dependencies.

This will also give us (Microsoft) time to implement new features from this new standard version like:

• Allow the usage of custom http verbs like "QUERY" #2600
• Streaming
• Suggestions are welcome

Describe the solution you'd like

Since this upgrade ultimately relies on Microsoft.OpenAPI upgrading from 2 to 3, and containing a few minor breaking changes.

I'm guessing the work here will be something along the lines of:

• upgrade the asp.net and Microsoft.OpenAPI dependencies where required
• upgrade swagger ui when they ship support for 3.2.0
• tests
• ship a preview to "closely follow apsnet 11 preview 2"

I'm creating this issue to give a heads up, and I remain available for any questions :)

#3786 is already active to adopt .NET 11 previews. There's an action item for 3.2 in the TODOs there, and there's also #3646 for if support was added independently of .NET 11.

Excellent! This is well underway. I knew you were on top of things since you interacted on the PR for aspnet but wanted to make sure a "proper heads up" was provided. I hope it helps and is not noise :)
