This commit also replaces Arch Unit packageInfoShouldBeNullMarked() rule
by either configuring requireExplicitNullMarking = false when the whole
module does not have JSpecify annotations, or explicit @NullUnmarked
when some have and some don't.

This commit upgrades our test suite to use JUnit 6.0.1 and removes the
systemProperty("junit.platform.discovery.issue.severity.critical", "WARNING")
configuration from spring-test.gradle, so that all discovery issues will
fail the build for the spring-test module as well.
In addition, this commit prevents potential AOT test scanning failures
for JUnit 4 tests by setting the
"junit.vintage.discovery.issue.reporting.enabled" configuration
parameter to "false" in TestClassScanner.

Closes gh-35740
This commit upgrades the build to use Gradle 9.1.
To achieve that, the following changes were necessary.
- Stop using Groovy safe-navigation operator (?.) in
framework-api.gradle due to a NullPointerException.
- Switch from the io.github.goooler.shadow plugin to the
com.gradleup.shadow plugin, since the former is no longer maintained
and the latter is a fork that replaces it.
Closes gh-35508
This commit simplifies our dependency management for JUnit artifacts by
making use of the junit-jupiter and junit-platform-suite aggregator
artifacts.
Closes gh-35127
Now that we are using JDK 18+ (currently JDK 24 -- see JavaConventions
in buildSrc for details), we can reinstate links to JUnit 5 Javadoc APIs.
Closes gh-27497
This commit revisit the build configuration to enforce the following:
* A single Java toolchain is used consistently with a recent Java
version (here, Java 23) and language level
* the main source is compiled with the Java 17 "-release" target
* Multi-Release classes are compiled with their respective "-release"
target. For now, only "spring-core" ships Java 21 variants.
Closes gh-34507
