Replace the retired adopt setup-java distribution with temurin in the Java 25 migration

[jkschneider]

AdoptOpenJDK is retired in favor of Eclipse Temurin and actions/setup-java marks distribution: adopt as deprecated. The migration raised java-version to 25 and left the distribution as it was. UpgradeToJava25 now runs the existing SetupJavaAdoptOpenJDKToTemurin before raising the version.

Found by a team of coding agents reviewing a Moderne run of org.openrewrite.java.migrate.UpgradeToJava25 over eight open-source repositories (run 20261003103223-WtyA8). The issue is setup-java-retired-distribution in the run's io.moderne.RecipeIssues data table, and the fix was discussed and reviewed on the run's message board. A row from the table, as a generalized example:

The migration retains retired AdoptOpenJDK rather than selecting its Temurin successor for Java 25. (spring-projects/spring-petclinic, .github/workflows/maven-build.yml)

Before:

What the recipe produced:

steps:
  - uses: actions/setup-java@v4
    with:
      java-version: '25'
      distribution: adopt

Expected:

  - uses: actions/setup-java@v4
    with:
      java-version: '25'
      distribution: temurin
