Redirects plugin does not work with URLs - only relative paths

[a-ys1]

Describe the Bug

When using the redirects plugin:

Example 1: This does not work

Example 2: This works

If you do as in Example 1, you have to prepend the process.env.NEXT_PUBLIC_SERVER_URL in each route (e.g [slug]) to the url. On this line:
https://github.com/payloadcms/payload/blob/main/templates/website/src/app/(frontend)/%5Bslug%5D/page.tsx#L51

Otherwise the PayloadRedirects-component will look for a redirect with the URL matching the relative path.
https://github.com/payloadcms/payload/blob/main/templates/website/src/components/PayloadRedirects/index.tsx#L17

So, the redirects plugin says "From URL" but actually needs a relative path as of now.

A solution could be to prepend the NEXT_PUBLIC_SERVER_URL to the url-prop inside the PayloadRedirects-component since that somewhat encapsulates the redirect logic.

Reproduction Steps

1. npx create-payload app - select website template, next coming options are irrelevant
2. Create a page called first-testpage
3. Create a page called second-testpage
4. Delete the page in step 2
5. Add a redirect with the From URL as [BASE_URL]/first-testpage
6. Set the to To URL Type as [BASE_URL]/second-testpage
7. Visit [BASE_URL]/first-testpage, you should get a 404
