Correct protocol for port 5514

Port 5514 *needs* to be **udp**, as noted in the upstream documentation (https://help.ui.com/hc/en-us/articles/218506997-UniFi-Ports-Used).

Noticed when looking at logs on an access point that showed: `failed to send log data to $address:5514 via udp`. Updating to udp corrected reachability.

Ran the change through `doc-builder` to pop out a `GENERATED.md` and all points in the `README.md` where the port is referenced looked fine.
