Add another identifier for detecting code signing identity

[marwanhawari]

Problem:

I am registered in the Apple Developer program, but create-dmg was not detecting my code signing identity. When I run:

security find-identity -v -p codesigning

my stdout looks something like:

  1) XXXXXXXXXXXXXXXXXXXXXXXX "Apple Development: Marwan Hawari (XXXXXXXXXX)"
     1 valid identities found

Currently create-dmg looks for Developer ID Application: or Mac Developer: in the stdout so it was not automatically detecting a valid code signing identity.

Solution:

This PR allows create-dmg to use Apple Development: when automatically detecting if the user has a code signing identity.
With this change, everything works correctly now. I can manually verify that the final dmg was signed using the following (which create-dmg does anyway):

codesign ${dmgPath} --display --verbose=2

Not sure when Apple started using Apple Development: though. For reference, I'm on macOS 13.1 and joined the developer program in 2021. Or maybe I just don't fully understand the code signing identity lol.
