Ability to serve UI behind a proxy on a path

[lpil]

Describe the feature request

Hello!

We wish to run the Gatus UI on an address like https://internal.example.com/status using a reverse proxy (i.g. nginx, caddy).

This works for the HTML, but the static files use absolute URLs staring with /, so rather than going to the correct proxied address of https://internal.example.com/status/css/app.css they go to https://internal.example.com/stats/css/app.css, without the status segment.

Would you accept a PR changing these URLs to be relative? So that the application can be served with any prefix?

Thanks,
Louis
