Default branch is sometimes main instead of master

[SC-Samir]

Hello 👋

The instructions on the CLI mention pushing to the master branch, but in my case, I had to use main for it to work correctly (because I have a new version of git)

Specifically, here's the line in question from the CLI code:

cli/apps/create.go

Line 42 in 2ce715c

fmt.Printf("App '%s' has been created\n", app.Name)

It will be useful to get the default branch using the git library and display it instead of always displaying master.
