RFR: 8323181: JavadocHelperTest.java OOMEs with Parallel GC and ZGC

[Thomas Schatzl]

Hi all,

  please review this small fix to increase max heap size for the test to let it pass with GenZGC and Parallel GC as well.

The test has at least 660m of live data, so the default 768m provided by testng is too small for these collectors.

Testing: local testing

Hth,
  Thomas
