Make PATCH request in Blocks Assistant boilerplate work like in Collabo Community API server

[samuko-things]

Issue description

Currently in the blocks-assistant-boilerplates the PATCH UPDATE request requires the request body to be in this format:

[
    {
        "propName":"name",
        "value": "string"
    },
    {
        "propName":"age",
        "value": number
    }
]

Instead, we want the PATCH UPDATE request to receive the request body in a single object format rather than an array of property-value format (just as is done in the Collabo Community API server ) as shown below:

{
     "name": string,
     "age": number,
}

Expected behavior

The PATCH UPDATE request should now receive the request body in a single object format rather than an array of property-value
