[7.x][ML] Improve stability of stratified splitter tests (#58180) (#58224)
The main improvement here is that the total expected
count of training rows in the test is calculated as the
sum of the training fraction times the cardinality of each
class (instead of the training fraction times the total doc count).

Also relaxes slightly the error bound on the uniformity test from 0.12
to 0.13.

Closes #54122

Backport of #58180
