ocis returns text/plain content-type not application/json like oc10 when requesting with ?format=json

[saw-jan]

Describe the bug

When requesting with ?format=json query param, ocis returns text/plain content-type
But oC10 returns application/json

requests:

• get capabilities
• get share recipients

In oCIS

curl -XGET -u admin:admin https://localhost:9200/ocs/v1.php/cloud/capabilities\?format=json -v

> GET /ocs/v1.php/cloud/capabilities?format=json HTTP/1.1

> Authorization: Basic YWRtaW46YWRtaW4=
> User-Agent: curl/7.68.0
> Accept: */*
