Upgrade to netflixoss 9.2.2 to publish candidates to maven central

[rpalcolea]

Hi folks,

This upgrades our netflixoss plugin to allow publishing candidates to maven central via:

• netflixossAltCandidateRepo=false (to support the old flag)
• netflixossPublishCandidatesToMavenCentral=true

Here is a sample project using this change: https://github.com/Netflix/netflixoss-sample-project/runs/2059598228?check_suite_focus=true
