Revisit format-id in the id property

[prachik1]

We’re from the Arc for VMware team and our swagger PR is currently blocked due to the failing ModelValidation check.

https://github.com/Azure/azure-rest-api-specs-pr/pull/13042/checks?check_run_id=14394025806

As part of this PR https://github.com/Azure/azure-rest-api-specs-pr/pull/12897, format arm-id has been added to the id property and this format validation is failing for our extension resources due to which we are seeing Swagger Model Validation failures.
Can you revisit your PR to allow supporting ARM IDs for extension resources also for id property, as these are valid ARM IDs.
