[sonic-mgmt] install newest az-cli to mitigate old version az-cli issue

[yejianquan]

Why I did it

Fix the issue that azure-cli version is too old.
With apt-get install, we will install the old version of azure-cli: (2.0.81+ds-4ubuntu0.2)
This version can't use azure keyvault command: Azure/azure-cli#17981
Following https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux?pivots=apt#option-2-step-by-step-installation-instructions to install the newest version of azure-cli

Can you take this chance to move installation of the dependencies to the top apt-get install?
