GH11 Add an "update_resource" command

[IanHopkinson]

Purpose

Version for this PR: 2024.3.1

The aim of this PR is to add a command "update_resource" which updates a resource given a dataset_name, resource_name and a file path. If the resource specified does not exist then it is added at position 0 with description provided by the --description flag.

Incidentally error reporting is improved for "update" so that if there is an authentication error this is reported explicitly.

• Update a resource #11

Major file changes

The main action happens in hdx_utilities.py. There is a new test file test_integration.py which runs against HDX stage. If a new resource is added then it is put in first position, this is done by first adding the resource then reordering in an explicit separate step. This works but it is not how the hdx-python-api library is expected to work. An issue is raised to investigate this further #17

Minor file changes

Minor documentation changes
