[openapi-diff-runner] [DEP0169] DeprecationWarning: url.parse() behavior is not standardized and prone to errors

[mikeharder]

Our breaking change workflows may fail with this error on Node 24:

[DEP0169] DeprecationWarning: url.parse() behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for url.parse() vulnerabilities.

Root cause is a bug in autorest v2:

• [v2] [DEP0169] DeprecationWarning: url.parse() behavior is not standardized and prone to errors autorest#5174

For now, we can workaround by using node 22 instead of 24, for breaking changes. Update these workflows to use node 22 instead of 24:

.github/workflows/breaking-change-code.yaml
.github/workflows/breaking-change-cross-version-code.yaml

This was fixed by ignoring stderr in @azure/oad:

• [Openapi-Diff] Bump autorest to ^3.8.0 and fix stderr handling openapi-diff#459

So openapi-diff-runner can now use Node24.
