[BUG] NotAuthorized component links to /beta/beta/settings/my-user-access in beta

[josejulio]

Describe the bug

When the NotAuthorized component shows in a beta environment, it has an invalid link: /beta/beta/settings/my-user-access

To Reproduce
Steps to reproduce the behavior:

1. Go to a page that shows the NotAuthorized component in a beta environment.
2. See where the My User Access link points to.
3. Click it.
4. See 404 error.

Expected behavior
Link should be: /beta/settings/my-user-access

Desktop (please complete the following information):

• OS: Fedora 33
• Browse:r Chrome
• Version: 87.0.4280.66 (Official Build) (64-bit)

Additional context
I think the issue is because all the beta pages have the <base href=/beta/> and the component also adds the ./beta

@karelhala @ryelo Wondering if is OK from your POV to remove that beta/ from https://github.com/RedHatInsights/frontend-components/blob/master/packages/components/src/Components/NotAuthorized/NotAuthorized.js#L19

@josejulio yeah, that's definetly a bug, when we used both ./ and calculated the beta ourselves.
