Maven plugin uses Maven Core 3.1.0 while its dependencies bundle Maven Core 3.5.0 (Maven 3.5 interceptor and CLI)

During the upgrade to Parent POM 2.32 I noticed that ReactorManager#getTopLevelProject() APIs have been deleted in 3.2.1: https://abi-laboratory.pro/java/tracker/compat_report/maven/3.1.1/3.2.1/2fc05/src_compat_report.html

It causes compilation failure with Maven Core 3.5.0, because MavenBuild#preBuild() and MavenBuild#postBuild() actually use this method.

There are two ways to fix it:

• Keep Maven Core on 3.1.0 and ignore upper bounds for this case
• Update API usage (my plan for now)
