Offline plugin still not available?

[mddeff]

I'm trying to follow the offline build tutorial. In #3784 it was established that the offline module was in the "Insider" edition of mkdocs-material. Since then, the offline plugin seems to no longer be only for "Insiders" (as indicated in the docs by the icons). Yet, when I try to build with the latest docker image

I get:

# docker
docker run --rm -it -v ${PWD}:/docs ghcr.io/squidfunk/mkdocs-material build   
ERROR   -  Config value 'plugins': The "offline" plugin is not installed

Aborted with a configuration error!

# alpine image with mkdocs-material-9.5.5-r1 installed
mkdocs build
ERROR   -  Config value 'plugins': The "offline" plugin is not installed

Am I missing something obvious?

You seem to be running an older version of Material for MkDocs in the container. The latest is 9.6.16. I am not a Docker user but guess you may need to pull a fresh version with docker pull ghcr.io/squidfunk/mkdocs-material:9.6.16?

You do have the Material theme set, right?

It helps if you read the docs from the beginning.... Thanks!
