Fixes #23709 - Fix ajaxRequestAction failure dispatch

The FAILURE action dispatched in ajaxRequestAction is not
aligned with the bookmarks, powerStatus and statistics
reducers:
- Moving to axios returns Error object instead of a string
- The payload doesn't contain "id" but "item"...

Fixes #21624 - eslint update to airbnb-base

Replace existing custom rules with airbnb-base config.
Eventually we'll want to to move to the full airbnb config
with react and a11y.
