Description of problem:
When try to import the Helm chart "httpd-imagestreams" the "Create Helm Release" page shows a info alert that the form isn't avaiable because there isn't a schema for this helm chart. But the YAML view is also not visible.

Info Alert:

Form view is disabled for this chart because the schema is not available

Version-Release number of selected component (if applicable):
4.9-4.14 (current master)

How reproducible:
Always

Steps to Reproduce:

1. Switch to the developer perspective
2. Navigate to Add > Helm Chart
3. Search and select "httpd-imagestreams", click the card and then Create to open the "Create Helm Release" page

Actual results:

1. Form / YAML switch is disabled
2. Info alert is shown: Form view is disabled for this chart because the schema is not available
3. There is no YAML editor

Expected results:

1. It's fine that the Form/ YAML switch is disabled
2. Info alert is also fine
3. YAML editor should be displayed

Additional info:
The chart yaml is available here and doesn't contain a schema (at the moment).
