build!: Upgrade to Java 25 to benefit from various optimizations

BREAKING CHANGE: ORT is now compiled to bytecode level 69, so programmatic
users of ORT libraries have to use Java 25 as well. Also, the `Gradle`,
`GradleInspector`, and `SBT` package managers will now use Java 25 by
default unless overridden via their `javaVersion` plugin options.
