Use toml-test-for-java for TOML compliance tests

[yawkat]

Summary

• replace the external toml-test checkout workflow with the published toml-test-for-java test artifact
• run valid/invalid TOML 1.0 corpus cases directly from embedded TomlTestSuite fixtures
• remove the dedicated TOML compliance workflow now that the default Maven verify run covers these tests

Verification

• Confirmed at.yawk.toml.test:toml-test-for-java:0.1.0-2.2.0 resolves from Maven Central
• Ran ./mvnw -B -q -ff -ntp -pl toml -Dtest=ComplianceValidTest,ComplianceInvalidTest -Dmaven.repo.local=/home/opc/dev/agent-work/jackson-text683/.m2-public-check/repository clean test with a fresh local Maven repository
• Ran git diff --check

Resolves #683

Pull request overview

This pull request streamlines TOML 1.0 compliance testing by switching from an external toml-test repository checkout to the published toml-test-for-java artifact, allowing the compliance suite to run as part of the normal Maven verify build.

Changes:

• Updated TOML compliance tests to use at.yawk.toml.test.TomlTestSuite fixtures (TomlTestCase) instead of filesystem-based corpus inputs.
• Added the toml-test-for-java test dependency and JPMS test-module requirement.
• Removed the dedicated GitHub Actions TOML compliance workflow now that ./mvnw verify covers these tests.
