[TASK] Resolve all phpstan errors in CorrelationId

The aspects array-key is always set because the
capture is not nested and filled in any case.
That means: If preg_match was successfull
(which is checked before), aspects have been found as well.

Executed commands:

  composer require --dev phpstan/phpstan:^1.12.6
  Build/Scripts/runTests.sh -s phpstanGenerateBaseline

Resolves: #105226
Releases: main, 12.4
