Community Contributions - Additional 'Well-identifiable' Secret Detection token patterns

Related to #340002 (closed).

This issue is for the community to contribute "Well-identifiable" Secret Detection token patterns to be added to our Secret Detection rules.

If you are a vendor for a cloud SaaS platform and your service generates secrets tokens with well-identifiable prefixes, we'd love to our add it to our secret detection rules to run by default for GitLab secret detection. Please comment with the following:

1. name and URL of the cloud service
2. the regex pattern for your secret
3. the well-identifiable prefixe your service uses
4. a sample invalid token to test with your regex pattern. Multiple samples are welcome.
