It appears that the snyk-security plugin does not follow the standard release process (as explained in https://www.jenkins.io/doc/developer/publishing/releasing/.

As a consequence, the pom.xml inside the artifact is not properly formed. Especially the version field is not properly populated. See for instance the latest release 2.10.4 pom: https://github.com/jenkinsci/snyk-security-scanner-plugin/blob/a42a97bc8d2f47738bc4695d6b5934e4d131ae8f/pom.xml#L12.

This does not seem to impact the Open Source Update Center, but it impacts other Update Centers. Would you mind reviewing the release process?
