tools/CI: scan repository with trivy security scanner (yarn.lock, com…

…poser.lock)

- run scan on each push/pull request update
- can be run locally using make test_trivy_repo
- exit with error code 0/success when vulnerabilities are found,  as not to make the workflow fail, a separate periodic run that exits with code 1 should be added in parallel
- update trivy to v0.43.0
- https://github.com/aquasecurity/trivy/releases/tag/v0.43.0
- also consider TRIVY_EXIT_CODE when running trivy on the latest docker image
- ref. shaarli#1531
