internal/licenses: Increase unidentified words allowed in atc exception

Increase the number of unidentified words accepted by the atc-dependency
license exception for package and repo names by 1.

The current atc license exception works for the Apache Traffic Control
master branch, but the 5.1.x release branch license
(https://github.com/apache/trafficcontrol/blob/5.1.x/LICENSE) only has
66% coverage. This CL brings it up to 79%.

For golang/go#44968
