.web-docs: remove community flag

The community flag does not exist in the integrations API, so while the
action succeeds, the documentation failed to be processed, hence why we
end-up with an incomplete integration for the plugin at the moment.

Once this PR is merged, this will need to be re-ingested in order for
the integrations API to process the plugin once more.
