Ensure compliance with new Strava Garmin API Brand guidelines

[dvmarinoff]

Garmin’s new API Brand Guidelines now require even downstream developers
that do not connect directly with Garmin to include brand attribution when data
is sourced from a Garmin device.

...

Garmin Data Attribution: Activity data obtained through the Strava API may include
data that requires attribution to Garmin. Therefore, if your application displays
information derived from Garmin-sourced data, you must display attribution to Garmin
in the form and manner required by Garmin’s brand guidelines.

Garmin’s API Brand Guidelines are scheduled to take effect on November 1, 2025.
