The other primary consumer of this is make/conf/jib-profiles.js. The make/conf dir would make sense to me.

The challenge here is creating a set of variables that are suitable enough for both config files to consume. For
BootJDK, we never bothered with bumping the version for updates, and I very much doubt we will do that in the future
for github actions, so a plain major version 14, and soon 15, would be preferred from my point of view. This is however
not enough for jib-profiles.js (yet) so we can't really share bootjdk config for now anyway. For jtreg, we specify 5.1
and b01 as two separate metadata values. For gtest we specify the version as 1.8.1.
