Apply Gradle wrapper retry metadata

[alvarosanchez]

Summary

• Adds the applicable Gradle wrapper retry metadata from the Micronaut Project Template: retries=0 and retryBackOffMs=500.
• Leaves the wrapper distribution at Gradle 9.3.0; distributionUrl and validateDistributionUrl=true are unchanged.
• Keeps wrapper scripts, wrapper jar, plugin code, publishing, workflows, dependency catalogs, docs, and samples unchanged.

Template Applicability

Applied:

• Repository-neutral wrapper retry metadata.

Intentionally skipped:

• Template Gradle distribution upgrade and wrapper binary/script churn, because the Gradle Plugin support matrix needs explicit maintainer intent for that change.
• Template workflow, publishing, .agents, and generic dependency/catalog changes, because they do not apply directly to this Gradle Plugin Portal-published repository.

Verification

• git fetch origin master DEV-663-manually-apply-template-changes-to-the-micronaut-gradle-plugin
• git rebase origin/master
• git diff --check origin/master...HEAD
• ./gradlew --version --no-daemon

Current CI

• GraalVM Latest CI and CLA passed.
• Java CI / build (25) failed in existing :functional-tests:test OpenAPI/KAPT cases with NoSuchMethodError: StaticJavaParser.parseJavadoc(...) and related generated Kotlin test compile failures.
• Recent master Java CI runs are also failing, so this appears unrelated to the wrapper metadata-only diff; no DEV-663 branch change is requested from code review for that failure.

Paperclip

Fixes DEV-663.

Project routing note: QA did not create a separate intake artifact for this routine issue, but QA and Security both approved the master branch target. Code review selected the matching open Micronaut organization project set: 5.0.0-M3 and 5.0.0 Release.

No PR-visible assets are required because this is a wrapper metadata-only change with no rendered output or generated review artifact.
