[Fix] Make python API doc generation in Microsoft-hosted Agent (#21766)
### Description
<!-- Describe your changes. -->
### Motivation and Context
1. Python API doc needs to be merged from a fork, but 1ES self-hosted
pool is only for one github repo.
2. ubuntu-latest will be install numpy above 2.0 by default, and current
python API doc generation doesn't support it.
So I pin numpy < 2.0.0
