ci: do not fail the build if vulnerabilities are found

The `exit-code` resulted in build failures even for LOW, MEDIUM
vulnerabilites with trivy-action 0.14.0, since the `severity`
configuration is ignored for `sarif` format unless we also set
`limit-severities-for-sarif` (but we want the full report).
