A change to ansible-config has the plugin env vars and the script that generates this docs page needs to be updated to also now handle plugins:
ansible/ansible#49627

closing, should be moved to https://github.com/ansible/ansible-documentation/

The page says, "Other environment variables to configure plugins in collections can be found in Index of all Collection Environment Variables.". The link goes to a page mentioning all environment variables defined by plugins (https://docs.ansible.com/ansible/latest/collections/environment_variables.html#list-of-collection-env-vars) that are not already mentioned on https://docs.ansible.com/ansible/latest/reference_appendices/config.html#environment-variables.

I would actually remove the current page(s) and document how ansible-config can dump files with 'ini', 'env vars' and 'yaml variables' for the configurations. Otherwise I would expect both ini and variable pages corresponding to the same.
