New E2E-Tests for data view

[Marcelfrueh]

Purpose

Adds two new E2E-Tests for data view: Testing functionality of table view and time series view. Validates that new graphs are displayed correctly and that filtering is working.

Remarks

PR introduces (a) breaking change(s): no

PR introduces (a) deprecation(s): no

Unfortunately, both tests are flaky: Changing the filter settings throws the error: ResizeObserver loop completed with undelivered notifications. Errors occur when adding a filter (line 55 in table.spec.ts and line 77 in timeSeriesSave.spec.ts)

[Marcelfrueh]

Added 5 new Tests for different widgets in data view: Now testing the functionality of table, time series, 2D-correlation, distribution, heatmap, map and indicator.
To avoid the error message "ResizeObserver loop completed with undelivered notifications" when adding a filter, the test for the filter is excluded from the UI tests.

The setup of this test seems to be the same for each of the widget tests. Can you please extract this in a seperate utils file?

[tenthe]

Is it possible to add this also to the new utils function? Maybe it is possible to change the time range before adding the widget.

[tenthe]

Thanks a lot for implementing those tests. I had only one comment regarting the setup code for eacht test. This seems to be very similar. Maybe we can introduce a function in the DataLakeUtils class that is used in eacht test for set up.

Done!
