docs(oidc): remove stale back-channel logout unimplemented notice (#12660)

<!-- CURSOR_AGENT_PR_BODY_BEGIN -->
# Which Problems Are Solved

- The OIDC logout guide still claimed Back-Channel Logout was not
implemented in ZITADEL, even though the feature is supported and
documented elsewhere.

# How the Problems Are Solved

- Removed the outdated "This is not yet implemented in ZITADEL" callout
from the Back-Channel Logout section of the logout guide.
- Added a short note linking to the dedicated [OIDC Back-Channel
Logout](/guides/integrate/back-channel-logout) guide.
- Left the Front-Channel Logout "not yet implemented" callout unchanged,
since that mechanism is still unsupported.

# Additional Changes

- None.

# Additional Context

The back-channel logout is a mechanism on the server-side and the user agent does not have to do anything.
The user will log out from all clients even in the case the user agent was closed.

ZITADEL supports OpenID Connect Back-Channel Logout. See [OIDC Back-Channel Logout](/guides/integrate/back-channel-logout) for how it works and how to configure your application.
