Adapt the documentation to Blue Ocean deprecation

[MarkEWaite]

Describe your use-case which is not covered by existing documentation.

Blue Ocean will be deprecated in July 2026 per the CloudBees announcement. I think that the main body of Jenkins documentation should describe Pipeline Graph View rather than describing Blue Ocean. We should retain the Blue Ocean pages for reference by users that are still running it, but should not include Blue Ocean in the primary documentation flow.

The Blue Ocean status entries on the existing pages should be updated to note that it will be deprecated July 2026.

I don't think we should remove the existing pages, but they should not be so prominently visible in the table of contents.

Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.

Blue ocean deprecation has been mentioned in community.jenkins.io posts like:

• Thinking about Blue Ocean

Blue ocean deprecation has been discussed many times in documentation office hours, including:

• October 2, 2025
• May 15, 2025
• May 2, 2024
• April 26, 2024

Are you interested in contributing a fix?

I'll probably submit an update to the status entries, but am unlikely to implement the full replacement.

Screenshots

I also archived the Docker image with a note pointing here: https://hub.docker.com/r/jenkins/blueocean.

The Docker image stays available but in read-only mode (so no breakage but user are warned in the DockerHub and in their Docker Desktops)
