Uupdated semantic commit message pattern matching and logic

• Updated pattern matching for ^fix: and ^feat: to that it also now matches fix(scope): style.
• Added to echo statements to clearly echo previous version and new version
• Added logic to skip publishing if there's no change in version, if not a SNAPHOT

Testing steps

• if snapshot version and a ^chore.* commit message, script should output No new package snapshot to publish as commit is type=chore
• if snapshot version and commit message is not chore then script should output New package snapshot to publish: ${VERSION}
• if not a snapshot version and commit message is anything other than ^BREAKING CHANGE.*, ^fix.*, or ^feat.*, the .version script should output No new package version to publish
  • otherwise the script should display the new version: New version to publish: ${VERSION}
• test that commit messages fix: and feat: publish a new version (if not a snapshot version)
• test that updated patterns to match a component name like fix(component): and feat(component): also now publish a new version (if not a snapshot version)
• test that if a new version is to be published (PUBLISH_NEW_VERSION=true), the new rule for .publish:maven runs the job
  • otherwise if PUBLISH_NEW_VERSION=false, .publish:maven job is skipped
• confirm that package with expected version is correctly published to Pacakge Registry
