Version

2.42.0

Storage Type

In-memory

Installation Type

Official Helm chart

Expected Behavior

no 404s when viewing anything other than the root

Actual Behavior

when you set the config like this

config:
  issuer: https://<host>/

there is a double / which results in 404s.

ex: viewing the known hosts results in
https://<host>//.well-known/openid-configuration and a 404 is returned

removing the / from the issuer fixes this:

config:
  issuer: https://<host>

however it would be simpler to remove a trailing / for more painless deployments

Steps To Reproduce

1. deploy dex using the official helm chart, adding the issuer url as shown above with the trailing slash issuer: https://<host>/
2. go to the UI and click on discovery. this will result in a 404
3. remove the trailing /
4. test again and the 404 is gone
