Description

As a contributor
I need to set up local environment for bridge-in-tech-backend and send screenshots,
so that I can provide proof of the same.

Fixes #244

Successful register of user BIT

Login MS

Login BIT

Checklist:

• My PR follows the style guidelines of this project
• I have commented my code or provided relevant documentation, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• Set up local environment (this means both BIT and MS version for BIT backends must run successfully)
• Provide a screenshot of a successful response when a user login on Swagger UI (if you haven't done this, you have to register a user first).
