Updates to github action workflows and some bug fix after upgrading t…

…o Kibana 7.10 (opensearch-project#139)

- Upgrade `cypress` to 5.6.0, `cypress-io/github-action` to @v2 to avoid set environment variable errors. 

- Changes in workflow files to get Kibana version from `kibana.json` instead of `package.json`. This is a change due to where the Kibana version is defined after upgrading to Kibana 7.10.

- Update the `getRollups` API to prevent error getting metadata when there are no rollup jobs present. 

- Add a `null` check in `ApplyPolicyModal` since sometimes `this.context` is found to be `null` before adding toast notification. So far this did not occurred in other parts adding toast notification.
