Bump lz4-java from 1.11.2 to 1.11.4 to fix GHSA-gm45-99xc-r7wv,
GHSA-343h-94h5-c4wr and GHSA-mcr4-qmvw-px4g.
https://github.com/yawkat/lz4-java/releases/tag/v1.11.4

Compression level constants are unchanged, so CompressionType needs no
update. 1.12.0 tightens input validation and can be evaluated
separately.

Hi @chia7712 @m1a2st, regarding my comment in the description

Note that there is also a 1.12.0 release but but based on the description it might contain breaking changes without additional security patches. Needs further investigation maybe in a separate ticket and the current Jira can handle the immediate CVE fix

If you prefer I can also do the update straight to 1.12.0 in this ticket but needs some additional time to verify the changes

We can update it to 1.11.4 in this PR to keep things simple :)
