Analytics will no longer be recorded. If we want to keep this a link to historical data we can update this line to explain that.

Updated the analytics line in README.md to clarify that it links to historical data only, with a note that analytics are no longer being recorded.

### TCD install attribution

During Testcontainers Desktop client authorization users are redirected to `https://testcontainers.com/desktop/authorized/`.

This page sends an `attribution` event to [Mixpanel](https://eu.mixpanel.com/project/2717988/view/3254192/app/events#pYPErQ1bEeiU) that links any attribution information in the users cookies (utms, referrer etc) to the client install ID.
This page sends an `attribution` event to [Mixpanel](https://eu.mixpanel.com/project/2717988/view/3254192/app/events#pYPErQ1bEeiU) that links any attribution information from the URL parameters (utms, referrer etc) to the client install ID.

The code for this page is found in `/layouts/authorized/baseof.html`.

The script that saves that attribution data to the users cookies is in the Google Tag Manager container.

With all of the client side reason for this page removed, we could add it to the redirects in netlify.toml. We may also wan't to update the TCC code to not redirect users to this page anymore.

Added redirect in netlify.toml to redirect /desktop/authorized/ directly to https://app.testcontainers.cloud/api/auth/login with a 302 status code. This eliminates the need for the client-side redirect page.
