feat: add feature to the List Users API to filter users by skill

[battuAshita]

Description

Added a new feature to filter both users and verified users based on their skill. The 'app/api/dao/user.py' and the 'app/api/resources/user.py' files have been updated.

Fixes #759

Type of Change:

• Code

Code/Quality Assurance Only

• New feature (non-breaking change which adds functionality pre-approved by mentors)

How Has This Been Tested?

I have included a test_dao_filter_by_skill.py file to 'tests/users'. Both the test cases that I have written have been passed successfully.

I have made changes to the code such that we will be able to filter based on the skill even when they are not exactly matched. Like if we search for "Creative", we will be able to get the users with skill "Creativity". Please review this change :)
