[ML] [Accessibility] Suggestion: Add table stats to job filter input's aria-label attribute

[elasticmachine]

Original comment by @aphelionz:

There's already an item to add an aria-label to the job filter input... why not have it read off these helpful stats as well?

Original comment by @jgowdyelastic:

will this not be confusing to have all of these stats read off from a component that is largely unrelated to them?

Closing as the filter input has been replaced with a standard eui filter bar in the recent jobs management rewrite.
