Upgrade docs build to use python v3.10 (#2083)

## Upgrade docs build to use python v3.10

* Fixed build dependencies so docs build now works with python v3.10
* Minimum requirement for Olive is now python v3.10
* Delete unused pipelines (replaced by OneBranch pipelines)

Known Issue - Olive still uses pydantic v1.x which is soon to be sunset.
Docs build is dependent on sphinx which has deprecated support for
pydantic v1.x.
