Upgrade plugin parent POM from 4.53 to 4.57

[basil]

This is needed for the forthcoming PCT multi-module mode to pull in the fix for JENKINS-62658 via jenkinsci/maven-hpi-plugin#453. I tested this successfully with the latest update to the multimodule project branch of PCT, which is now doing mvn process test-classes rather than mvn install, therefore requiring the fix for JENKINS-62658. With these changes you can now successfully run mvn process-test-classes in the root directory of the repository, which was not possible with the old version of Maven HPI plugin.

To test this PR I ran:

$ git checkout blueocean-parent-1.27.3
$ git clean -fxd
$ mvn clean process-test-classes  # failed before, passes now
$ mvn -Dtest=InjectedTest -Djth.jenkins-war.path=/home/basil/src/jenkinsci/bom/target/local-test/megawar.war -DoverrideWarAdditions=true -DoverrideWar=/home/basil/src/jenkinsci/bom/target/local-test/megawar.war -Djenkins.version=2.396 -DuseUpperBounds=true -Dtest=InjectedTest hpi:resolve-test-dependencies hpi:test-hpl surefire:test # passes
