**Resolves: elastic#180660**

## Summary

In this PR I am fixing a problem of the `Install All` button being
re-enabled when entering the page again.
I am fixing only the UI problem here, only for the scenario described in
the ticket: single user interacting with single instance of Kibana.
During investigation I discovered and discussed with the team other
scenarios which may lead to race condition when installing rules, but
the team agreed to work on them separately.

The fix uses `useIsMutating` hook to check that the mutation is pending.
Such information is added to the `AddPrebuiltRulesTableContext` and then
used to disable the `Install All` button in the component.
