[FEATURE] Support for checkboxes in the metadata forms

[SjoerdManger]

We, at Amsterdam UMC, would like to use checkboxes in our metadata forms. However, right now the titles of said checkboxes aren't displayed in the metadata forms in Yoda. We would like to see this fixed so we can implement checkboxes.

The current situation ("Data Type" and "Subject Type" missing as title"):

The desired situation:

A code snippet of our JSON form:

"definition_datatype": {
         "type": "object","definition_datatype": {
         "type": "object",
         "title": "Data Type",
         "properties": {
            "i Biological samples": {
               "type": "boolean",
               "title": "i Biological samples",
               "default": false
            },
            "ii Genetic / omics data": {
               "type": "boolean",
               "title": "ii Genetic / omics data",
               "default": false
            },
            "iii Imaging data": {
               "type": "boolean",
               "title": "iii Imaging data",
               "default": false
            },
            "iv Qualitative data and quantitative questionnaires": {
               "type": "boolean",
               "title": "iv Qualitative data and quantitative questionnaires",
               "default": false
            },
            "v Physiological data": {
               "type": "boolean",
               "title": "v Physiological data",
               "default": false
            },
            "vi Synthetic data": {
               "type": "boolean",
               "title": "vi Synthetic data",
               "default": false
            }
         }
      }

and

"datatype": {
         "$ref": "#/definitions/definition_datatype",
         "title": "Data Type"
      }
