Add secret scanning for Azure secrets

Azure has a set of secret formats that [it used to recommend scanning for](https://www.powershellgallery.com/packages/AzSKPreview.AzureDevOps/1.0.9/Content/Framework%5CConfigurations%5CSVT%5CAzureDevOps%5CCredentialPatterns.xml), before it paywalled them behind Github Advanced Security. I note that you have the AWS scanner [here](https://github.com/pre-commit/pre-commit-hooks/blob/main/pre_commit_hooks/detect_aws_credentials.py) - would it be accepted if I was to build an equivalent python file for the Azure secret formats [published by Microsoft here](https://www.powershellgallery.com/packages/azskpreview.azuredevops/1.0.6/content/framework/configurations/svt/azuredevops/credentialpatterns.xml)? Thanks!
