[BUG] Volume Open in Databricks Fails - Wrong URI

[bryan-1913214]

Describe the bug
With the Unity Catalog explorer built into the extension now, viewing a Volume offers the same Open in Databricks option as tables, but when you try to open the Volume it takes you to a "table" referenced by the name of your volume and fails.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Unity Catalog'
2. Click on a catalog and schema where the volume exists
3. Click on a volume
4. Click on 'Open in Databricks' button
5. See object that doesn't exist (unless you have a table by the same name; and that's possible?)

Additional context
Specifically, it's trying to route to a table like

When the volume object actually is
