.azurepipelines: Use Python 3.10.6+

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3891

Changes the Python version used in pipelines to 3.10.6 or greater
since that version introduces a fix (bp0-47231) for inconsistent
trailing slashes in tarfile longname directories.

This is required for stuart_update to succeed when handling a
web_dependency (e.g. GCC ARM compilers).
