"The Java thread stack size specified is too small. Specify at least 384k" for ppc64le arch

[Mathieu-Ferraton]

Running cassandra:4 on ppc64le produces this error: The Java thread stack size specified is too small. Specify at least 384k.

Looking at the ppc64le specific section of the 4.0 Dockerfile, substitution of the -Xss256k value with -Xss512k is tried in $CASSANDRA_CONF/jvm.options file (3.11 legacy, file doesn't exists in 4.0), and in $CASSANDRA_CONF/cassandra-env.sh (3.0 legacy, option not set from there in 4.0):

In cassandra 4.0, setting -Xss256k in JVM_OPTS is done in $CASSANDRA_CONF/jvm-server.options, so the corresponding Dockerfile should reflect that change.
