description: Tests that Temporal.PlainYearMonth meets the requirements for built-in objects

function object with the characteristics described in 10.3. Unless specified otherwise, the
[[Extensible]] internal slot of a built-in object initially has the value true.
Unless otherwise specified every built-in function and every built-in constructor has the
Function prototype object [...] as the value of its [[Prototype]] internal slot.
