fix(route53): cannot add tags to HostedZone (#7531)

We don't classify `HostedZoneTags` as the tagging property
since it follows a naming convention where it's not called `Tags`.

`HostedZoneTags` are also an array of type `HostedZoneTag` objects that
enforce the `{Key: "...", Value: "..."}` convention.

This is similar to `FileSystemTags` property for `EFS`

Closes #7445
