## Description

### Steps to reproduce

1.  Enable High Contrast Mode
2.  Navigate to the Share modal in any work package as someone with sharing rights
3.  Check any checkbox
4.  Observe the checkbox's background

### What is the buggy behavior?

Primer checkboxes have no background making them almost impossible to tell whether they're checked or not

### What is the expected behavior?

Primer Checkboxes should have an acceptable contrast ratio as seen on the Primer Lookbook when High Contrast Mode is enabled:
