fix: remove spaces from json raw

[cristianoventura]

This PR removes spaces between attributes of a JSON that was being displayed in the raw version.

Before:

{ "key": "value", "array": [ 1, 2, 3, 4 ] }

After:

{"key":"value","array":[1,2,3,4]}

• Inspect a JSON response
• Check that the Raw tab doesn't contain spaces between properties for JSON content
• Check that no functional changes affect the Raw tab for other content types such as HTML
