Tutorial: Update value of MAP_TEMPLATE in a practical step of rose-app.conf

[mo-wilfwilson]

The lines a little above say:

Copy the remaining environment variables defined in the forecast
task within the flow.cylc file into the rose-app.conf
file of the forecast application, replacing any values already
specified if necessary. Remove the lines from the flow.cylc file
when you are done.

And MAP_TEMPLATE has a new value in flow.cylc for me, so shouldn't the answer look like I've indicated in the diff?

Okay, probably not, because then the workflow doesn't work:

So maybe the code for flow.cylc that the tutorial creates is wrong? i.e. shouldn't contain the line MAP_TEMPLATE=$CYLC_WORKFLOW_RUN_DIR/lib/template/map.html?
