Feature request: Rule to disallow usage of `@phpstan-ignore-*` annotations without error identifier

[eliashaeussler]

Hi,

I built a custom rule in https://github.com/eliashaeussler/phpstan-config/pull/53 that disallows the usage of @phpstan-ignore-line and @phpstan-ignore-next-line annotations without error identifiers.

Is this something you'd consider useful as a part of the strict-rules package? If so, I'd be happy to provide a PR. If not, that's fine as well :)

Cheers!

Just for a reference, the same thing can be achieved with ~30 lines of php code. Example: https://github.com/shipmonk-rnd/phpstan-rules/pull/246/files

Another approach could be to introduce a config parameter that allows for skipping reading of this token. Then PHPStan acts as if the token is not there at all, and thus the error that it tries to hide still shows up. Might even require less code.

I like that. Super simple and easy to do. Just one more config param to be passed to PHPStan\Parser\RichParser. If @ondrejmirtes likes that too, I can implement that.

Not a fan. Less code isn't always better. I'd rather write more code and have the error messages under control.

In my opinion @phpstan-ignore-line and @phpstan-ignore-next-line should always work to ignore errors because it's a core feature. But we should report usage of these comments as a new error if the user chooses to.

We already have this information available in AnalyserResult (getLinesToIgnore, getUnmatchedLineIgnores) so it's something that could be easily achieved with a few lines in AnalyserResultFinalizer.
