[ios] Set correct location service activity type for cycling

[biodranik]

CLActivityTypeOtherNavigation
The value that indicates positioning for activities that don’t or may not adhere to roads such as cycling, scooters, trains, boats and off-road vehicles.

CLActivityTypeFitness
The value that indicates positioning during dedicated fitness sessions, such as walking workouts, running workouts, cycling workouts, and so on.

Note that in the current car navigation mode position will be closer to Apple's road network data:

CLActivityTypeAutomotiveNavigation
The value that indicates positioning in an automobile following a road network.

The changes are opposite to the PR's description. Or I missed something?

Or if we prefer "Other" for bicycle, pedestrian should also be "Other", according to the description ..

CLActivityTypeFitness

This activity might cause the system to pause location updates when the user doesn’t move a significant distance over a period of time.
The system disables indoor positioning.

@vng good point, agree. Updated the PR to drop fitness. @kirylkaveryn documentation says that location updates may be stopped in some conditions. Does our current implementation properly resumes these updates after they have been stopped? Because if not, it may cause #799

[kirylkaveryn]

I'm not sure about this change.

Documentation says that other may pause location updates too.

This activity might cause the system to pause location updates when the vehicle doesn’t move a significant distance over a period of time.

Pausing updates doesn't mean "stopping" - that location is disabled. It means that if you having a rest, location will not be updated until you continue walking/biking.

Location always starts updating when a user continues activity. I haven't faced any issues with that.

Some articles says that Fitness type is more precise.
Maybe the Other will be enough. But as Apple said:

pedestrian navigation tracking that’s not tied to a road network, paths, or trails.

During the biking and hiking it's usually important to tie to the dedicated path...

Our users do not walk on Apple-approved paths. They use OSM paths, and often go where there are no any paths )

Pausing is ok to save battery, it is important to restart again though )

Aren't docs say that location updates should be restarted manually?

After a pause occurs, it’s your responsibility to restart location services again when you determine that they’re needed. Core Location calls the locationManagerDidPauseLocationUpdates: method of your location manager’s delegate to let you know that a pause has occurred. In that method configure a local notification that has a UNLocationNotificationTrigger to notify when the user exits the current region. The message for the local notification should prompt the user to launch your app again so that it can resume updates.
