[Discover] re-add recent datasets

[kavilla]

Description

Recent datasets was remove apart of:
#8816

This is because without workspaces enabled this fine but with it enabled then recent datasets was persisting across workspaces that potentially dont have the datasource available that the dataset is referencing.

The original fix we wanted to do was to save datasets with workspace id in session storage. To give users the ability to switch workspaces and have access to the previous visit of this workspace and recent datasets.

However, when investigating: the workspace is apart of core start application but dataset service is apart of a service that is apart of the setup lifecycle.

The second path could be storing the workspace in the dataset meta information. This will help with another issue as shared URLs currently take you out of a workspace. So if we add this to the dataset meta information we could recreate the dataset within workspace context. While also persisting the dataset in a specific workspace recents datasets. But the work wouldn't be large but it wouldn't necessarily small. Since the data plugin pretty much has to be enabled for the application to do anything but workspaces isn't as required (although it's a really sick feature).

The feature work should avoid placing it in a way that the data plugin is now a dependency of the workspaces service
