Incorrect test expectation in type-calendar-valid.js

[anba]

The underscore tests in

test262/test/intl402/DisplayNames/prototype/of/type-calendar-valid.js

Lines 29 to 32 in 86e2399

	assert.sameValue(typeof displayNames.of('123_abc'), 'string', '2 segments, minimum length, underscore');
	assert.sameValue(typeof displayNames.of('12345678_abcdefgh'), 'string', '2 segments, maximum length, underscore');
	assert.sameValue(typeof displayNames.of('123_abc_ABC'), 'string', '3 segments, minimum length, underscore');
	assert.sameValue(typeof displayNames.of('12345678_abcdefgh_ABCDEFGH'), 'string', '3 segments, maximum length, underscore');

should all be moved to https://github.com/tc39/test262/blob/main/test/intl402/DisplayNames/prototype/of/type-calendar-invalid.js.

The underscore character "_" is only accepted for the sep production when the backwards-compatibility extensions are enabled. But in ECMA-402 we only accept Unicode BCP 47 locale identifiers, so identifiers without the backwards-compatibility extensions.
