[DOCS] Remove PrintCompressedOopsMode JVM option (#73741) (#73954)

Changes:
* Removes a reference to the
  `-XX:+UnlockDiagnosticVMOptions -XX:+PrintCompressedOopsMode` JVM option. This
  option is no longer supported.
* Combines `Xms/Xmx` recommendations for compressed oops.

Closes #71644.

 The more heap available to {es}, the more memory it can use for its internal
 caches. This leaves less memory for the operating system to use
 for the filesystem cache. Larger heaps can also cause longer garbage
