Why need perl?
As I far as I understand, this issue should install perl by he/she self in his/her Dockerfile, it's not a azure-cli requirement.

The docker doesn't need git either if we just want to run azure-cli.
I guess git was put in the docker for user's convenience. As some git functions rely on perl, we may also put in perl.

Understood, if that so, I would recommend to put perl ahead of git since it's more fundamental that git, many other softwares rely on it.
