[FEATURE]: Add Gitpod Setup

[rohitkbc]

Motivation

Having gitpod ready repo makes contribution easy and also it does not requires to setup environment locally

I have worked on similar issue in PHP repo of TheAlgorithms TheAlgorithms/PHP#130

I would like to work on this feature

Examples

Other repos like Python and GoLang in TheAlgorithms use gitpod.

I'm mostly indifferent to Gitpod support; I wouldn't use it myself or recommend it to our contributors, but it is a low maintenance cost feature (cf. the discussion on the PR to add Gitpod configuration to the Lua repo), so I am not strongly opposed to it, and would accept a PR.
