Add Risk Acceptances workflow testing

[Alexdev8]

This test checks that risk acceptances can be accepted, refused and revoked and that a non approver user cannot be selected as an approver for a risk acceptance.

Duration: approx. 28s

This test could maybe also include the check that a non approver user cannot effectively approve a risk acceptance he is not assigned to.
However, this addition would significantly extend the duration of the test and I didn't think it would be worth

The logedpage parameter removed in the commit 6d418a3 is not in fact unused. It is a fixture called by Playwright at the start of the test and removing it inevitably cause it to fail.

I don't know how to pass the CodeFactor check with this parameter. Maybe just by calling logedPage in the test for no other reason than the GitHub check. Or we can just ignore the CodeFactor check.
