[TASK] Add possibility to define allowed browser console errors

Allowed console errors are only valid for one test execution.
Thus, these exceptions need to be declared for every test case.

```
use TYPO3\TestingFramework\Core\Acceptance\Helper\Acceptance;

class SomeCest
{
    public function someTest(Scenario $scenario)
    {
        $acceptance = $scenario->current('modules')['\\' . Acceptance::class] ?? null;
        $acceptnance->allowBrowserError('/Found invalid token [[:digit:]]{40}/i');
        ...
```
