[python] etag/match-condition for x-ms-blob-if-match

In azure-storage-blob [get-tags](https://github.com/Azure/azure-rest-api-specs/blob/401749fc21a4ffec2f8d182b9d01d28964342a2a/specification/storage/Microsoft.BlobStorage/routes.tsp#L1433) operation there is an if-match and if-none-match that has the header property [@header("x-ms-blob-if-match") etc. ](https://github.com/Azure/azure-rest-api-specs/blob/401749fc21a4ffec2f8d182b9d01d28964342a2a/specification/storage/Microsoft.BlobStorage/models.tsp#L2816). Other if-match parameters with @header(If-Match) generated out as etag/match_condition parameters. Should theses getTags ifMatch parameters also generate as etag/match_condition instead of if_match/if_none_match?
