Azure CLI docker container base Linux image is now Azure Linux

Starting from the version  2.64.0 of Azure CLI, the base Linux distribution of Azure CLI is now Azure Linux.

Impact of the change

• az commands are unaffected.
• shell commands specific to Alpine will not be functional (ex: apk).
• The following GitHub action will use the new image and could impact scripts using Alpine specific commands or components

Addressing the change in GitHub actions

If you are using GitHub actions, remove any Alpine-specific commands from the `inlineScript` in azure/cli action to achieve a smooth transition to this new image.
