Interview Task - Create User Update Endpoint

[Kaizen-NeilHardy]

For this task, I would like you to:

• Create an update endpoint for the user to update an existing user.
• The caveat is that emails can be empty and can also be updated to empty.

Things to watch out for:

• If a username is blank then a user will never be able to login.
• If a user is without a password they will also not be able to login.

Optional Tasks - Only if you have time within the two hours.

• Add in interfaces to align with SOLID methods.
• Add in unit tests for your new method.
• Improve the other endpoints where possible.
