## Overview
Updates `eslint-plugin-jest` and enables the recommended rules with some
turned off that are unhelpful.
The main motivations is:
a) we have a few duplicated tests, which this found an I deleted
b) making sure we don't accidentally commit skipped tests
This PR:
* Increases test retry count to 2 so that flaky tests have more of a chance to pass
* Ideally most e2e tests will run for all React versions (and ensure DevTools elegantly fails if React doesn't support its features). However, some features aren't supported in older React versions at all (ex. Profiling) Add runOnlyForReactRange function in these cases to skip tests that don't satisfy the correct React semver range
* Fix should allow searching for component by name test, which was flaky because sometimes the Searchbox would be unfocused the second time we try to type in it
* Edited test Should allow elements to be inspected to check that element inspect gracefully fails in older React versions
* Updated config to add a config.use.url field and a config.use.react_version field, which change depending on the React Version (and whether it's specified)
