Fix the deletion of a workspace via UI.

What issues does this PR fix or reference?

The new pop-up is present when users tires to delete a workspace.
Now the user needs to select the checkbox and click on a Delete button.

EDIT: related issue #8542

Deleting workspace by checkbox and deleting button doesn't work in 100% cases. In the part of the cases workspace keep displaying and correct displaying require window refreshing.
So that is why I disagree with this approach and strongly recommend keep current approach.

[Katka92]

Current flow is to go to the workspace details and there click Delete button. After that, a new pop-up appears, where the user needs to select the checkbox and press again Delete button.
I've fixed the part with the pop-up, the flow stays the same.
Current flow is not working as nightly tests are failing on that, so if you don't like this approach, please suggest something else.
