Bugfix/trusted host pattern failing

[andreashager]

Description

The problem was that the crawler could not crawl websites in the frontend on the production server. The problem was a trusted host pattern fail due to the check of the server port that was never been set: https://github.com/TYPO3/typo3/blob/10.4/typo3/sysext/core/Classes/Utility/GeneralUtility.php#L2929

Additionally a type mismatch error on the crawler log in the backend was fixed.

Maybe this could be the same problem as described in #757 🤔

I have

• Checked that CGL are followed
• Checked that the Tests are still working
• Added description to CHANGELOG.md (github-handle is optional)
• Added tests for the new code

Looks good to me, can you please take care of the Static Code Analysis warnings from cs-fixer and PHPStan

[andreashager]

I changed my code that the CS-Fixer and PHP Stan warning is gone 😄
