Temporal: don't allow comparison operators when comparing two Temporal values.

[rafael-cx]

Temporal does not support .valueOf(). Therefore, when accidentally using comparison operators it will throw during runtime. See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/Instant/valueOf

Temporal.Instant.prototype.valueOf()
The valueOf() method of Temporal.Instant instances throws a TypeError, which prevents Temporal.Instant instances from being implicitly converted to primitives when used in arithmetic or comparison operations.

A linting rule checking this would prevent runtime issues.
