[Enhancement] Make software development experience easier

[ajay-bhargava]

Purpose

Following on from this thread in the Brilliant discord, it is apparent to me that the current state of this repository doesn't clearly articulate the dependencies required to run Tasks > Build in VSCode to craft a suitable application.hex to flash onto a nRF52480 SDK.

What this change imparts

I've added a few files to make the Dev experience a bit more streamlined, pending further input from the support team regarding essential libraries needed to develop. Namely these changes include:

• Devcontainer.json
• DockerFile
• docker-compose.yml

If merged and all libraries described, a user should become empowered to build application.hex without having to install the necessary binaries on their local machine.

Thank you!

Thanks for considering this PR!

Hello,

I humbly submit an improvement to the existing codebase to aid developers. This allows most of the make utilities to be pre-installed in a Docker container to make the build process faster and less error prone for people trying to locate libraries.
