foris-controller: update to version 2.1.3

Backport for TOS 5.3.x

Fixed:

• networks: backport enabling managing of interfaces on Turris 1.x

Fix for turris/foris-controller/foris-controller#236 (closed)

How to test it

Before backport

Changing interface assignment of interfaces between bridges or unassigned in reForis shows success (the green banner), however nothing has changed - no "Reloading network..." spinner and after reload of reforis page interfaces stays the same as before.

After backport

Changing interface assignment of interfaces between bridges or unassigned in reForis should show success. "Reloading network..." spinner should appear and changes should be applied and visible on reForis Interfaces page.
