Is your feature request related to a problem? Please describe.
I see that Gitleaks has a rule for detecting 1Password service account tokens. I'd be interested in adding support for detecting 1Password secret keys.

Describe the solution you'd like
Detect potential 1Password secret keys.

Describe alternatives you've considered
I haven't been able to find any software that can already do this.

Additional context
I can put in a PR to add this functionality if approved. 🚀 🚀 🚀
