Remove any references to "community meeting"

The "Kubernetes Community Meeting" has not occurred for several years. However, there are still references to this defunct meeting within the kubernetes/community repository.

Since k8s.dev consumes content from this repository, these outdated references are appearing in search results and confusing new contributors looking for meeting information.

Proposed Changes

- Search for and remove references to the "Community Meeting" in the documentation.

Search the documentation in the kubernetes/community repository for references to “Community Meeting” and review how that content is consumed by k8s.dev. Remove references to the defunct meeting, then repeat the search to confirm the outdated information is gone.
