Is there an existing issue for this?

I have searched the existing issues

Current behavior

When JSON data containing large numbers is shown in the JSON response view, the numbers are incorrect (rounded).

JSON sent by server:

{"an_integer":555555555555555555,"a_float":555555555555555555.555}

Shown in JSON view in Hoppscotch:

{
  "an_integer": 555555555555555600,
  "a_float": 555555555555555600
}

What is expected to be shown:

{
  "an_integer": 555555555555555555,
  "a_float": 555555555555555555.555
}

Steps to reproduce

Create a JSON file with the following content:

{"an_integer":555555555555555555,"a_float":555555555555555555.555}

Run a static HTTP server (your choice)
Send a GET request to fetch your JSON file
Open the JSON response view and see incorrect numbers

Environment

Seems like JavaScript is rounding off large numbers in JSON.parse() and JSON.stringify() operations. Guess it'd be better to use any libs like lossless-json on responses.
