Update the AD Kibana plugin workflows

[ohltyler]

Change 1 (NOTE: this issue applies to all Kibana plugins using cypress for their integration tests)

Since GitHub actions has deprecated the use of set-env, the old version of the Cypress action (cypress-io/github-action@v1) breaks the workflows.

All calls to this old action need to be updated to any version >= 2.3.1. For example, the issue will be fixed if using the current latest version:

uses: cypress-io/github-action@v2.5.0

Change 2
Since it is necessary to change the built zips to a new naming convention using camelcase, all references to the zip files and unzipped plugin names will need to be changed. For AD Kibana, the following changes will need to be made:

Zip references:
opendistro-anomaly-detection-kibana-$plugin_version.zip -> opendistroAnomalyDetectionKibana-$plugin_version.zip

AD plugin references:
opendistro-anomaly-detection-kibana -> opendistroAnomalyDetectionKibana

Thanks!

Addressed Change 1 in this PR #482

Change 2 is being taken care of by @peterzhuamazon

As we discussed change 2 is finalized with Kibana Plugin Owners.

All kibana plugins will change their names to camel cases, so ./bin/kibana-plugin install would work in 7.10.0.
New naming convention format:
opendistro<CamelCasePluginNames>Kibana-<4Digit Plugin Version>.zip

Kibana Naming Convention:
------
opendistroAlertingKibana-1.12.0.x.zip
opendistroAnomalyDetectionKibana-1.12.0.x.zip
opendistroGanttChartKibana-1.12.0.x.zip
opendistroIndexManagementKibana-1.12.0.x.zip
opendistroNoteboooksKibana-1.12.0.x.zip
opendistroQueryWorkbenchKibana-1.12.0.x.zip
opendistroReportsKibana-1.12.0.x.zip
