What is this action supposed to do? Is this a typo?

https://github.com/temporalio/helm-charts/blob/main/charts/temporal/templates/server-job.yaml#L73-L74

curl -X PUT --fail --user "$ES_USER:$ES_PWD" $ES_SCHEME://$ES_HOST:$ES_PORT/_template/temporal_visibility_v1_template -H "Content-Type: application/json" --data-binary "@schema/elasticsearch/visibility/index_template_$ES_VERSION.json" 2>&1 &&
\
curl -X PUT --fail --user "$ES_USER:$ES_PWD" $ES_SCHEME://$ES_HOST:$ES_PORT/$ES_VISIBILITY_INDEX 2>&1

The second PUT is without any payload, is this correct? I get status 400 Bad request and I think it's a correct response to such a request.
I used to init/migrate_up dependent DBMS and ES manually, so:

curl -sSL 'https://raw.githubusercontent.com/temporalio/temporal/main/schema/elasticsearch/visibility/cluster_settings_v7.json' |
        curl --user "${temporal_es_user}":"${temporal_es_pass}" -X PUT -H "Content-Type: application/json" \
                --data-binary @- --write-out "\n" "${temporal_es_addr}/_cluster/settings" && \
curl -sSL 'https://raw.githubusercontent.com/temporalio/temporal/main/schema/elasticsearch/visibility/versioned/v7/index_template_v7.json' |
        curl --user "${temporal_es_user}":"${temporal_es_pass}" -X PUT -H "Content-Type: application/json" \
                --data-binary @- --write-out "\n" "${temporal_es_addr}/_template/temporal_visibility_v1_template"

So:

• my 2nd curl query seems to do the same what your 1st one does;
• your script is missing my 1st query - I don't really know if it's mandatory/important, but I actually took it from your code somewhere in this repo (or from an image building repo, can't remember) - shouldn't this be added to the chain of actions there?
• your script does weird PUT without payload at the end, I think it is a typo and you probably wanted GET instead to get a 200 status response with the config/description of the created index.
