Implement Functionality to Delete a Skill

[andrew21-mch]

Allow users to delete skills from their portfolio. This includes removing the skill from the database and updating the displayed list of skills accordingly.

Steps to Complete:

Create a delete option (e.g., a button) next to each skill listed on the user’s dashboard.
Implement server-side processing to remove the skill from the database upon user confirmation.

Acceptance Criteria:

Users can delete skills, and the skills are removed from both the database and the UI.
The deletion is immediately reflected on the user’s dashboard without requiring a page refresh.
