[BUG] Power Automate Editor Import OpenAPI 3.0 - allOf not changed

Type of Connector

Custom Connector

Name of Connector

GitHub Gists

Describe the bug

I was able to successfully import the connector definition (after removing non-Gists-related definitions) from:
https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.json
In the Swagger Editor, I can see that the definition has been downgraded to 2.0. However, the allOf keyword has still been included. So, I have two questions:

1. Does the Editor saving without an error mean that the custom connector can be used with the allOf parameters?
2. The paconn CLI validate command completes with warnings, but should these be fixed before submission as an Independent Publisher connector? (I may fix and submit anyways, as it is only two warnings)

Is this a security bug?

No, this is not a security bug

What is the severity of this bug?

Severity 3 - Minor issue

To Reproduce

Import OpenAPI definition that includes allOf keyword (I'm guessing this is similar for oneOf, anyOf, and not as well)

Expected behavior

Editor downgrade removes the need for allOf keyword

Environment summary

Install Method (e.g. pip, interactive script, apt-get, Docker, MSI, edge build)
CLI version (paconn --version)
OS version
Shell Type (e.g. bash, cmd.exe, Bash on Windows)

Additional context

None

Start with the OpenAPI definition linked in the issue and reproduce the import in the Swagger Editor, focusing on the OpenAPI 3.0 to 2.0 downgrade and its handling of allOf. Then run the paconn CLI validate command and compare the editor output and warnings with the expected behavior that unsupported composition keywords are handled before submission.
