Additional Extension Recommendations (#53)

<!-- markdownlint-disable-next-line first-line-heading -->
## Description

<!-- Describe your changes in detail. -->
This adds a couple of additional recommended extensions for use with
this blueprint:
* Black (formatter)
* SonarQube for IDE (code quality and directly linked to NHS England
engineering red lines)

This change also makes a minor amendment to how the users.json file is
located (using `os.getcwd()` instead).

## Context

<!-- Why is this change required? What problem does it solve? -->
This ensures tools are available for linting code and checking code
quality by default.

## Type of changes

<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply. -->

- [x] Refactoring (non-breaking change)
- [x] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would change existing
functionality)
- [ ] Bug fix (non-breaking change which fixes an issue)
