json-module/parse-error.html tests implementation-defined filename property on error event

Rationale

This test checks some details of an ErrorEvent thrown when an imported JSON module has a syntax error.

assert_true(e instanceof ErrorEvent, "ErrorEvent");
assert_equals(e.filename, new URL("parse-error.json", location).href);
assert_true(e.error instanceof SyntaxError, "SyntaxError");

But, the value of the filename property is implementation-defined. See https://html.spec.whatwg.org/#report-an-exception and https://html.spec.whatwg.org/#extract-error.

All browsers currently fail this test. The check for filename should be removed, or maybe the test should be removed from the focus area.

Seems fine to me.
