Enable collectfasta for Azure blob storage

[jasongi]

Description

Collectfasta was disabled for Azure storage as unsupported in this PR:
#5476

It is now supported as of Collectfasta 3.3.0 (PR: jasongi/collectfasta#7), so it can be re-enabled by undoing the changes in the above PR by adding Azure to the cloud_provider check i.e

{%- if cookiecutter.use_whitenoise == 'n' and cookiecutter.cloud_provider in ('AWS', 'GCP', 'Azure') -%}

adding the following setting

COLLECTFASTA_STRATEGY = "collectfasta.strategies.azure.AzureBlobStrategy"

Rationale

Faster asset upload when using Collectfasta
