fix ANTLR ATN version conflict between hibernate and cqengine

[lucastheisen]

• Brief description of changes applied
  • This fixes an ANTLR ATN verison conflict between upstream dependencies (hibernate and cqengine) by applying the upstream maintainers suggested workaround
• Test cases for all modified changes, where applicable
  • N/A, i could not come up with a small enough scenario
• The same pull request targeted at the master branch, if applicable
  • N/A, this PR is already targeted at master
• Any documentation on how to configure, test
  • N/A there is no documentation as it is a very minor build time change and to test, you would need to start up a cas that used both the google MFA and audit JPA and you got all the way through the authentication workflow to the point you got a response back from the google authenticator MFA (at least that is the point where this was failing from me and no longer does).
• Any possible limitations, side effects, etc
  • There are no limitations, and the only known side effect is a slighly larger dependency per the upstream maintainer of cqengine
• Reference any other pull requests that might be related
  • N/A this PR is a standalone
