[Build] Fixes

[riedgar-ms]

The Docs build was running out of disk space, so move to Large_Linux nodes (not sure what caused this, but it's not a high priority to run down).

Also fix a small issue in the Notebooks build. Since there are now two pytest invocations, we need to make sure that the second doesn't overwrite coverage results from the first.
