Adapt formatting of descriptions in example to new user interfaces

Adapt the format in the descriptions of the examples to the markdown rendering deployed on the reactor today.
Since today's deployment to the reactor, the catalog entries at https://catalog.botlab.org and https://reactor.botlab.org/catalog show bots descriptions as markdown.

The new UI uses the implementation from dillonkearns/elm-markdown#108 for the markdown parsing and rendering.

    The bot warps to an asteroid belt, mines there until the ore hold is full, and then docks at a station or structure to unload the ore. It then repeats this cycle until you stop it.
    If no station name or structure name is given with the bot-settings, the bot docks again at the station where it was last docked.

    This bot makes your travels faster and safer by directly warping to gates/stations. It follows the route set in the in-game autopilot and uses the context menu to initiate jump and dock commands.

    Some bots should consider the remaining time in the current session when choosing the next activity.
    This program gets and stores the session length limit set in the configuration interface.
    It also computes the remaining time as the difference between the present time and the configured limit and displays the result via the status text.

    This bot only sends a sequence of inputs to the window and then stops.
    As the example input sequence below shows, we can implement drag&drop operations by using the inputs `MouseButtonDown`, `MoveMouseToLocation`, and `MouseButtonUp`.
    A good way to test and visualize the mouse paths is to use this bot on a canvas in the MS Paint app.
