squirrel-sql: use supported JRE

[raboof]

Description of changes

The current version of squirrel doesn't support the current default JRE in nixpkgs (19). Since this is a property of squirrel-sql, changed it in squirrel-sql's default.nix.

Hello @raboof,

Have you seen [1]? The current version of Squirrel, the Java parts at least, do actually support Java 19 (as announced in the release notes[2])...however the launcher scripts are out of date and as far as I can tell just need to have newer version numbers added to a version check. I mean to add a patch for this, but it fell off my radar, so thanks for the reminder. Do you mind if we continue with this approach instead? I think it would be preferable to forcing users to have an older, extra JVM on their systems. I've created a PR for this fix: #235096

Thanks!
