Update Azure Cloud Shell API to the newer version

[PankajBhojwani]

Updates the api-version to 2023-02-01-preview when requesting for CloudShell settings and shell

Validation Steps Performed

Can still use Azure Cloud Shell through Windows Terminal

A few things to note:

• The new api-version introduces some new user settings, the main one being allowing Ephemeral sessions, which differs from Mounted sessions in that ephemeral sessions have no storage associated with them. As long as the user updates their user settings in the Azure portal to use ephemeral sessions, they will be able to use ephemeral sessions through Windows Terminal as well (with this change)
• We continue to not provide any user flow to change the azure cloud shell settings (so the user cannot change between ephemeral or mounted sessions within Windows Terminal, the same way they cannot change the preferred shell type)
• Users that haven't updated their azure cloud shell settings in the portal recently will be unaffected by this change (the new api-version is backward compatible with their old settings)
• Users who have updated their azure cloud shell settings in the portal but don't update Terminal with this commit will be unable to use Azure Cloud Shell via Terminal - we will attempt to access their new settings with the old api-version and that will fail
