Adapt Docker setup to latest changes

[tpetillon]

Fixes #5031, #5005.

Requires #4893, or any other solution for #5043.

The Docker setup is a quick and easy way to get an Openstreetmap-carto dev environment running, so it’s probably worth keeping it in a working state. This PR updates the startup script to take recent changes into account, such as #4978. It also updates the base images to more recent versions.

With this PR alone, setting up the containers fails because fonts cannot be downloaded. Applying #4893 allows testing the whole setup.

Many thanks for working on this. Some minor comments from giving it a test run:

docker-compose up import to import the data (only necessary the first time or when you change the data file).

It would be useful to add that that downloading and importing the water polygons table can take substantial time, and will be the rate limiting step when importing a small subset of OSM data (which will be the normal use case). It doesn't help that the message shown by get-external-data.py is "Checking table X" during download, which gives the impression that things have got stuck (why is "checking" taking so long?).

On the first run, import failed with "Max retries exceeded with url: /download/antarctica-icesheet-outlines-3857.zip (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x7f345affb7d0>: Failed to resolve 'osmdata.openstreetmap.de", which is odd because the website was functioning. It worked on repeating the docker-compose up import (again this seems to be more an issue/fragility of get-external-data.py rather than the docker set up per se).

[Haven't tested beyond the font import step. This fails with "scripts/get-fonts.sh: 11: curl: not found".]
