[RELEASES] Replace direct links to the release details page with links to open the release flyout

[ryan953]

At the time of writing I don't have a complete list of places that link to release details. There is a Release Hovercard thing that should also exist at all the callsites.

In the end we want all links in the app to:

• have a release hovercard, i assume this is already the case
• to open the new release flyout instead of linking directly to release details or the release list page

To help ease the migration the release flyout could have a link along the lines of "Click here to view the old Release Details page" so people can still get back to the old thing. This is probably a good idea, but TBD right now.
