PHP 8.2 | File::getMethodProperties(): allow for true in types

As of PHP 8.2, `true`, `false` and `null` will be allowed as stand-alone types. `true` can now also be used in union types (was already allowed for `false` and `null`).
The `true` and the `false` types are allowed to be nullable, the `null` type is not (but that's not the concern of this method).
Also see: https://3v4l.org/ZpfID

This commit adjusts the `File::getMethodProperties()` method to take `true` into account. `false` and `null` were already handled due to these previously already being allowed in union types.

Includes unit tests.
