Azure Detector Regex fix

[ankushgoel27]

Description:

Azure now uses a 40 char string as a secret for the service principal instead of 34 chars. Also, even both 34 and 40 char versions used [A-Z] which was missing from the current regex. I don't think there was a need for a v2 detector unless the format for the secret key was changed. This new regex will detect both 40 char and 34 char versions.

See this video for the 34 char version - https://www.youtube.com/watch?v=Kf1Tai_BkWU. At 3:19, it shows that the 34 char version also had [A-Z] in it.

Checklist:

• Tests passing (make test-community)?
• Lint passing (make lint this requires golangci-lint)?

I don't think there was a need for a v2 detector unless the format for the secret key was changed.

The new secrets are substantially different from the old ones. Length, allowed characters, fixed values, etc.

See #2985.
