[TASK] Support several Apache Solr versions

As incompatibilities can also occur in minor versions, all versions
will be explicitly tested and listed.

Currently tested and supported versions are: 8.11.1, 8.11.2.

It is always recommended to use the latest tested version.

Note: Apache Solr 8.11.3 is not compatible with default settings,
security fix "SOLR-14853: Make enableRemoteStreaming option global;
not configSet" is a breaking change and as EXT:solr relies on
stream bodies currently 8.11.3 cannot be used without activating
stream bodies.

Ports: TYPO3-Solr#3956
Resolves: TYPO3-Solr#3955
