oauth2-proxy: 7.5.0 breaks protected path /static, HTTP 404

Expected Behaviour

Protected resource can still host on /static, just like in 7.4.0

Current Behaviour

404 page not found on resources hosted on /static Caused by https://github.com/oauth2-proxy/oauth2-proxy/pull/2025

Possible Solution

Rolling back to 7.4.0

Steps to Reproduce (for bugs)

Host a resource that has content on /static, for example jupyter login to the oauth proxy

the page does not fully load, requests to /static get a 404 response

calling the proxy on port 8080

kubectl debug -n tools -it jupyterlab-98c75c5c8-8qxq8  --image=curlimages/curl -- curl "http://localhost:8080/jupyter/static/lab/main.bcccfe17b7cd76ace990.js?v=bcccfe17b7cd76ace990"
Defaulting debug container name to debugger-rtpwv.
404 page not found

calling the underlying service on port 8888

kubectl debug -n tools -it jupyterlab-98c75c5c8-8qxq8  --image=curlimages/curl -- curl "http://localhost:8888/jupyter/static/lab/main.bcccfe17b7cd76ace990.js?v=bcccfe17b7cd76ace990"
Defaulting debug container name to debugger-rtpwv.
(()=>... (a valid response)

Context

Will roll back for now
