### Description
Move Linux Github actions to a dedicated pool. Currently the
"orttraining-linux-ci-pipeline " is too slow.
### Motivation and Context
To speed up the running.
Current labeling bot over-applies many of the labels (e.g., ep:CUDA and
platform:windows) and is missing some of the APIs + EPs
Working on migrating this workflow to GitHub policies but would like to
use this fix in the meantime to avoid causing any issues w/ ORT 1.19
