[MNG-6847] Use diamond operator

[timtebeek]

Hi! Found MNG-6847 on the backlog (closed), but that had only been applied to apache/maven#315 itself, not the additional 36 projects that could still use those changes. Figured open this one as a first one to ask if you'd appreciate any more.

These PRs are trivial for me to create, but I would not want to cause any review burden. That's why I'm only starting with one, and not creating more unless I get a positive response here.

Here's a full list of projects that could still use these changes.

 38 apache/maven-scm
 20 apache/maven-wagon
 19 "apache/maven-shared-utils"
 12 "apache/maven-resolver-ant-tasks"
 11 "apache/maven-integration-testing"
 11 "apache/maven-doxia-sitetools"
 11 "apache/maven-apache-resources"
  9 apache/maven-shared-io
  9 apache/maven-resolver
  9 apache/maven-ear-plugin
  7 "apache/maven-changelog-plugin"
  7 "apache/maven-assembly-plugin"
  7 apache/maven
  6 apache/maven-ant-tasks
  5 apache/maven-site-plugin
  5 "apache/maven-dependency-plugin"
  4 "apache/maven-plugin-tools"
  4 apache/maven-ejb-plugin
  4 "apache/maven-doxia-linkcheck"
  4 "apache/maven-doxia-book-renderer"
  3 "apache/maven-shade-plugin"
  3 apache/maven-mvnd
  2 "apache/maven-project-info-reports-plugin"
  2 "apache/maven-install-plugin"
  2 apache/maven-dist-tool

  1 "apache/maven-project-utils"
  1 apache/maven-pmd-plugin
  1 apache/maven-jmod-plugin
  1 "apache/maven-jdeps-plugin"
  1 apache/maven-indexer
  1 apache/maven-doxia
  1 apache/maven-doap-plugin

@elharo would this be something you're willing to review as well? Welcome to direct me to others too.

For my future self and others; Use this link to re-run the recipe: https://app.moderne.io/recipes/org.openrewrite.staticanalysis.UseDiamondOperator?organizationId=QXBhY2hlIE1hdmVu

Thanks for the quick review @slachiewicz ; Would you be ok with me opening let's say six more starting from the top?

[slachiewicz]

Yes, sure. Thx fro help

[timtebeek]

Happy to help! I've opened a few more, all linked above, some of which need approval for the pipelines to run.
If it's alright with you I'll keep something in the range of five to ten open at a time, such that we get further along.

Open to other systems as well; there's a long tail of 1 or 2 cases per repository that might not make sense by itself.
