Add screenshots to the dev containers user guide:
- Running dev containers with sub-agents (index.md, working-with-dev-containers.md)
- Discovered dev containers with Start button (index.md)
- Outdated status with rebuild option (working-with-dev-containers.md)
- Display apps disabled (customizing-dev-containers.md)
Also deletes the outdated devcontainer-agent-ports.png.

The user guide jumped straight into integration details without explaining
what dev containers are. Now it opens with a brief orientation linking to
the spec, then explains this guide covers the Docker-based approach.
Converted several NOTE callouts to prose where they were just cross-references
or stacked unnecessarily. The Envbuilder index note was reframed to lead with
its strengths rather than "we recommend the other thing."
Also updates platform support to Linux only per current status.

Dev container admin docs were scattered across two locations: the Docker-based
integration under extending-templates/ and Envbuilder under managing-templates/.
There was no landing page explaining that two approaches exist or helping admins
choose between them.
This moves everything under admin/integrations/devcontainers/ with a decision
guide at the top. Dev containers are an integration with the dev container
specification, so integrations/ is a natural fit alongside JFrog, Vault, etc.
Stub pages remain at the original locations for discoverability.
New structure:
admin/integrations/devcontainers/
├── index.md # Landing page + decision guide
├── integration.md # Docker-based dev containers
└── envbuilder/
├── index.md
├── add-envbuilder.md
├── envbuilder-security-caching.md
└── envbuilder-releases-known-issues.md

docs: rewrite dev containers documentation for GA
Corrects inaccuracies in SSH examples (deprecated `--container` flag),
port forwarding (native sub-agent forwarding is primary), and
prerequisites (dev containers are on by default). Fixes template
descriptions: docker-devcontainer uses native Dev Containers while
AWS/Kubernetes templates use Envbuilder.
Renames admin docs folder from `devcontainers/` to `envbuilder/` to
reflect actual content. Adds customization guide documenting agent
naming, display apps, custom apps, and variable interpolation. Documents
multi-repo workspace support and adds note about Terraform module
limitations with sub-agents. Fixes module registry URLs.
Refs #18907
Updates the dev containers documentation to accurately reflect that the
feature is generally available and document all configuration options.
