feat(LibraryNavigator): added ability to view dataset properties

[kpatl1]

Summary
This PR implements dataset properties functionality for the VSCode extension, bringing feature parity with SasStudio online version. Users can now right-click on datasets in the Library Navigator and view comprehensive metadata including creation dates, modification dates, dataset labels, compression information, and detailed column information.

Testing
Went into SASStudio and viewed properties for identical datasets and made sure that the information matched.

Fixes #1537

Overall looks good to me. Will defer to @scottdover to approve. Thanks.

@kpatl1 , have you considered having an option inside table viewer to see that same/similar info directly without having to leave the table viewer panel? Agreed that this is a nice-to-have, but just wondering what it would take to have this option in table viewer. Especially now we're working on adding additional capabilities in table viewer.

This looks great. Only had a couple minor things to mention

Hey @enzhihpp . These changes were accidentally merged prior to testing. Can we get this tested and perhaps create additional bugs for things that are oustanding?
