[BZ#1978785] Navigating to /providers route redirects to /providers/:providerType as a history.push(), should be history.replace() so that the back button works

[mturley]

If you click the Providers nav link, you get two entries pushed into your browser history (first the root providers page, then a redirect to the tab for a specific provider type). Clicking Back in the browser takes you back to the root providers page which then redirects you forward again, there's no way to go back two levels.

If we change that history.push to a history.replace on this line: https://github.com/konveyor/forklift-ui/blob/main/src/app/Providers/ProvidersPage.tsx#L80 the root providers page will not end up in the history, and the Back button will work as expected.
