### Description of the change

While working on #5436, I noticed some errors during the YAML parsing;
well not errors, but unexpected (for me) values being returned by the
`genIn` method. In collections, the returned thing is not a js object,
but a custom data type from the YAML library.

This PR is just to convert collections (YAML sequences and YAML maps)
back to plain js objects (even if the function says `toJSON()` 😅

### Benefits

We will be able to use arrays and object fields in the form.

### Possible drawbacks

N/A

### Applicable issues

- fixes #5519

(following

### Description of the change

As pointed out by @dud225, we weren't enforcing the numeric validation
consistently in both the slider and the text input. Besides, we were
missing some json schema fields like `exclusiveMinimum` and
`exclusiveMaximum`.
This PR is to fix that.

### Benefits

Consistent param validation

### Possible drawbacks

N/A

### Applicable issues

- fixes #5520

### Description of the change

As per the discussion in
#5530, this PR is adding a
`featureFlags.schemaEditor` flag to enable the schema editor for those
users who really want it.

It is a work-in-progress feature until we also save the schema or use in
the backend.
