Update Rose Tutorial to use Canned Amazon Data

[wxtim]

Update tutorials after https://github.com/cylc/cylc-flow/pull/7044, changing rainfall data source to Amazon.

N.b. https://github.com/cylc/cylc-flow/pull/7044 and subsequently the update tutorials Workflow will be required prior to this passing automated tests.

To test locally cp -r ~/cylc-flow/cylc/flow/etc/tutorial/cylc-forecast-workflow ~/rose/metomi/rose/etc/tutorial/rose-suite-tutorial and follow the tutorials at https://metomi.github.io/rose/doc/html/tutorial/rose/suites.html#rose-suite-configurations.

Does the Rose tutorial now require the new HDF library thinggy?

Does the Rose tutorial now require the new HDF library thinggy?

Unclear - the only tutorial involving this new data which is ever going to work without Cylc/Cylc-Rose being installed is the rose task-run -O test tutorial, and that uses the data after it has been extracted to CSV.

I think that there is an implicit assumption that cylc-flow[tutorial] has been installed. Is there a reason that we haven't made this assumption explicit? Is there a risk of creating circular dependencies?

We would have to create an optional dependency to do this:

$ pip install metomi-rose[tutorial]

Where metomi-rose[tutorial] would depend on cylc-flow[tutorial].

I think that the tests are failing because I've lower-pinned Cylc to 8.6.1 - hopefully they'll pass once we've released that.
