[TASK] Compatibility with TYPO3 13

[saitho]

Just declaring compatibility in composer.json is enough to get it working in my frontend. Haven't looked at PHP files yet though.

can confirm. this PR works for us.

I just ran the TYPO3 "Scan Extension Files" Backendtool and looked through the files:

There are just two things that could be fixed/changed for the new v13 comp. release:

• Remove usage of TypoScriptFrontendController in TagRenderer and AssetsMiddleware
• Replace the contentPostProc-all Hook with AfterCacheableContentIsGeneratedEvent

The latter mentioned Event was only introduced in v12 though, forcing us to drop v10 and v11 support and release a new major version.

Imho these two changes are not "absolutly needed" :)

EDIT: If we would do the mentioned changes and therefore drop v10 support, we would in turn be able to cleanup/refactor/modernize the PHP code and take advantage php 8 features 🤓
