fix: run validation pipelines using latest `clas12Tags` semver tag
Created by: c-dilks
Better fix for #168 (closed) (supersedes #169)
Triggers clas12-validation
workflow run using the highest semantically-versioned tag from clas12Tags
.
- highest semantic version is preferred over latest tag, since there may be backports to older tags which occur in the git DAG later than semantically later tags
- assumes that tag is working
- ignores the
dev
tag, which appears to be moving; it's ignored because it is not a semantic version number - this automation is a better approach than choosing a fixed tag, since we may eventually forget to increment it
