[LintDiff][False positive][data-plane] The PostOperationIdContainsUrlVerb linter rule reports false positive for POST action

The PostOperationIdContainsUrlVerb rule of the azure-openapi-validator reports a false positive for a POST action operation that uses a ":" as the separator between the resource and action name, as recommended by the [Azure Guidelines](https://github.com/microsoft/api-guidelines/blob/vNext/azure/Guidelines.md#actions-url-pattern-for-collection-action).

To reproduce: run this command on an API definition that follows the POST action URL pattern:
```
autorest --v3 --spectral --validation --azure-validator --use=@microsoft.azure/openapi-validator@latest --input-file=
```

For example,
```
f=specification/attestation/data-plane/Microsoft.Attestation/stable/2022-08-01/attestation.json
autorest --v3 --spectral --validation --azure-validator --use=@microsoft.azure/openapi-validator@latest --input-file=$f
```

generates (among many messages):
```
- file:///Users/mikekistler/Projects/Azure/azure-rest-api-specs/specification/attestation/data-plane/Microsoft.Attestation/stable/2022-08-01/attestation.json:466:7

- file:///Users/mikekistler/Projects/Azure/azure-rest-api-specs/specification/attestation/data-plane/Microsoft.Attestation/stable/2022-08-01/attestation.json:130:9

- file:///Users/mikekistler/Projects/Azure/azure-rest-api-specs/specification/attestation/data-plane/Microsoft.Attestation/stable/2022-08-01/attestation.json:254:9
```

These are all false positives.

Note that the ":" may appear either after a path parameter or after a static path segment.
