ddoc/source/assert_writeln_magic.d should ignore nothrow unittests

[ntrel]

Otherwise when the reader clicks run/compile they will get an error about writeln not being nothrow. E.g. last example here:
https://dlang.org/phobos/std_algorithm_mutation.html#.move

A related issue is nothrow functions with asserts inside a non-nothrow unittest.

• It’s open and there’s no linked PR.
• Whether the reported issue still occurs can be determined by trying to reproduce it following the steps from the issue description.

Actually that's not exactly true - the unittest attributes are ignored. However if a function in the unittest has nothrow, any asserts inside will cause compilation errors.

I have tried to fix this but this bug/design makes it a PITA:
