The current security-scan-app and security-scan-container workflows are triggered on push and pull_request events. When dependabot triggers it with a push event, the resulting SARIF files can't be uploaded, due to a limitation.

From the Github Actions logs:

Warning: Workflows triggered by Dependabot on the "push" event run with read-only access. Uploading Code Scanning results requires write access. To use Code Scanning with Dependabot, please ensure you are using the "pull_request" event for this workflow and avoid triggering on the "push" event for Dependabot branches. See https://docs.github.com/en/code-security/secure-coding/configuring-code-scanning#scanning-on-push for more information on how to configure these events.

We might want to find a way to disable dependabot from triggering on such "push" events.
