Frontend: Unmasked variables value appears as masked in the CI/CD variables table

Problem

Unmasked CI/CD variables appear as masked in the CI/CD variables table. This is confusing as it's harder to understand the visibility of a given variable when scanning the variables table.

Steps to reproduce

1. Ensure you are a Maintainer/Owner of a project
2. Navigate to Your_Project > Settings > CI/CD
3. Expand the "Variables" section
4. Create a CI/CD variable, do not check "Masked"
5. Create another CI/CD variable, and check "Masked"

Solution

To avoid any confusion, the value of an unmasked variable should not be masked in the variable table.
