Minor changes to the "Download data" section of the console (#2278)

This is a small pull request in response to:
#2277

The changes are:

- Rename "Download data" to "Export data" in the menu (for no real
  good reason)
- Add credentialing date to the user table
- Change a header from "Projects" to "Published Projects" for clarity
