What this PR does

Small change which adds a message before running az ... delete actions for .clean make targets

As a new user I found it unsettling to see the following when running make clean and having to blindly answer yes

# make clean
Are you sure you want to perform this operation? (y/n): y
Are you sure you want to perform this operation? (y/n): y
Are you sure you want to perform this operation? (y/n): y

With this simple change, the user knows what operation they are agreeing to

An alternate option was to remove the @ and let make output the commands, but this also outputs the if conditions and is unnecessarily verbose
