Fix azure cli version parsing

[jubittajohn]

What this PR does

az --version 2>/dev/null | grep azure-cli |awk '{print $2}'

the above command which is used to retrieve the azure cli version also returns the keyword location in addition to the expected version, because the az --version also contains the keyword azure-cli in the path of the returned Python location.
Below is the output of the above command.

2.68.0
