This updates the required project language level from 11 to 17, which is the next LTS version. This is a breaking change, in that downstream projects will need to update their language level to match. As a benefit, though, we get to use JDK 17 features that we've previously refrained from using for backwards compatibility reasons. To showcase this, I've updated some of our test files to use text blocks to more naturally specify the schema template, and I've updated one callsite to use `Stream::toList` instead of `Collectors::toList`. This resolves FoundationDB#2360.

Ok with bumping to 17 👍
Adopters who are not on 17 yet will need to stay on 4.10.X
