Upgrade to jvm17

[clitnak]

• Upgraded gradle from 4 to 7
• Tried to be a little aggressive with brining build-time support to jvm 17, specifically removed nashorn dependencies and reimplemented differently.

For my own education. Is there a particular reason you went to 7.3.3 (which was released Dec 22, 2021). Did you try to go further and ran into issues or just went to a version that was the minimal required and called that good?

I'm not too worried about being on a 2 year old version (we have been OK with being on a 5 year old version), just want to know for future work (internal) work.

The scenario was:

Issue came up.
Googled issue.
Solved by upgrading to gradle 7.
Upgraded to gradle 7
Solved
(more issues ensued, but that is a different story, if I upgraded to the bleeding edge, the issues would have increased, for certain)

I'll circle back and see what a larger gradle upgrade would entail, but technically that is out of scope.

Yep. Don't even worry about circling back, that explanation gives me what I wanted which is, "We don't know for sure there are issue with additional upgrades (likely are) but didn't try". If Gradle 7 gives us what we need for this update (it seems to) we are good with Gradle 7
