Update Micronaut platform versions

[jamesfredley]

Summary

Update the Micronaut-related release dependencies for the Grails 8 line and keep the Forge metadata aligned with the Micronaut platform it actually builds against.

This addresses the release-audit follow-up around Micronaut platform promotion and stale dependency metadata:

• Grails-Micronaut moves from Micronaut platform 5.0.0 to 5.0.3.
• Grails Forge stays on the Micronaut 4 line and updates its embedded platform metadata to 4.10.16.
• The Micronaut-tied BOM dependency sets add explicit ASM 9.10.1 constraints required by dependency validation.
• Forge generator expectations are updated to match the emitted Micronaut platform version.

Why

The pre-release review called out Micronaut dependency promotion and stale BOM/Forge metadata as release-readiness cleanup. Keeping the root Grails-Micronaut island, Forge properties, generated Forge POM metadata, and validation constraints in sync avoids a release where generated apps or BOM checks disagree with the versions the build is actually using.

Verification

• ./gradlew validateDependencyVersions -PincludeMicronautProjects
• ./gradlew :grails-micronaut:compileGroovy -PincludeMicronautProjects
• ./gradlew :grails-forge:processResources
• CI completed all checks for the branch; TestLens reported all tests passed, with one Windows shell CLI test flake rerun noted as unrelated.

Note

Targeted Forge tests were attempted but blocked by the existing unrelated grails-data-graphql static compilation failure in the current 8.0.x tree.

Pull request overview

Updates Micronaut platform versions across the Grails/Micronaut “island” and Grails Forge, and introduces explicit ASM version constraints to satisfy dependency version validation for Micronaut-related BOMs.

Changes:

• Bumps Grails-Micronaut Micronaut platform version from 5.0.0 to 5.0.3 (root build).
• Keeps Grails Forge on Micronaut platform 4.10.16 and updates the corresponding Forge test expectation.
• Adds explicit org.ow2.asm:asm / org.ow2.asm:asm-util constraints (version 9.10.1) into the Micronaut-tied BOM dependency sets to support dependency validation.
