XS✔ ◾ Fetch Depth Docs

[muiriswoulfe]

Summary

This change updates the documentation to include instructions on fetching Git history during the checkout process in Azure Pipelines. It also reorganizes some sections for clarity.

This addresses #542.

Documentation Updates:

• README.md: Added a new section titled "Git History" with instructions on how to fetch Git history during the checkout step using actions/checkout with fetch-depth: 0.
• docs/azure-pipelines-task.md: Added a similar "Git History" section with instructions for both YAML pipelines and classic pipelines, including details on disabling 'Shallow fetch'.

Reorganization:

• docs/azure-pipelines-task.md: Moved the "Always Close Comment" section to follow the new "Git History" section and made minor text adjustments for clarity.
