Inconsistant Jenkins target version

[ikedam]

aws-codebuild-jenkins-plugin targets Jenkins 2.60.3, but its dependency targets Jenkins > 2.60.3.

Example: #128
You bumped script-security 1.56 to 1.75, but script-security-1.75 targets Jenkins-2.176.4: https://github.com/jenkinsci/script-security-plugin/blob/script-security-1.75/pom.xml @leoherran-aws

This results mvn hpi:run failed with:

Jul 03, 2022 4:03:06 AM jenkins.InitReactorRunner$1 onTaskFailed
SEVERE: Failed Loading plugin Script Security Plugin v1.75 (script-security)
java.io.IOException: Script Security Plugin v1.75 failed to load.
 - You must update Jenkins from v2.60.3 to v2.176.4 or later to run this plugin.

Same to other dependencies. Attached full error log: aws-codebuild-startup-failure.txt

You should upgrade also target Jenkins version.
It makes sense to introduce Jenkins plugin BOM: https://www.jenkins.io/doc/developer/plugin-development/dependency-management/#jenkins-plugin-bom
