Previously, "nested" time zone property bags were unwrapped up to one
level. That is, this object:
{
timeZone: {
// ...Temporal.TimeZone methods
}
}
would not be considered to implement the TimeZone protocol, but would have
its timeZone property used instead, if it were passed to an API that
required a TimeZone protocol object.
These nested property bags are no longer supported. Discussion:

In these tests, we should make a distinction in the name for clarity. It's
testing a time zone passed as a property in a property bag (either as an
argument, or as a relativeTo option), so name it accordingly as we do with
other tests in the same folder.
