## Why
`identity.unkin.net` moved from an internal `unkin.net` CA-issued cert to the LetsEncrypt `*.unkin.net` wildcard. The `oidc.config` block pinned the internal root as the *only* trust anchor, so argocd-server now rejects OIDC discovery with `x509: certificate signed by unknown authority` and SSO login is broken. The stock image trust store already carries the public roots.
## Changes
- Remove the `rootCA:` block from `argocd-cm`'s `oidc.config` for the `https://identity.unkin.net/application/o/argocd/` issuer.
- Replace the now-false internal-CA rationale comment with a one-liner noting the LE-issued cert needs no pin.
- Leave issuer, clientID, clientSecret ref, `requestedScopes` (incl. `ak_groups`) and `requestedIDTokenClaims` untouched.
