docs(vscode): include formatting information in CONTRIBUTING.md

[alestiago]

Description

Currently, the contributing file for the VS Code extension does not have any information regarding code formatting. The current formatting strategy is largely dictated by the Prettier [1] extension. This should be at least documented so other developers know how to format the project adequately. Ideally, we should introduce a npm script [2], such as npm run format that formats the project without the need of contributors installing an extension in their IDE. Note that this command should be equivalent to using the extension and should be compatible with the current analyser, eslint [3].

Requirements

• Include an npm script to format the VS Code extension project as the Prettier extension
• Document the use of a formatter in the VS Code CONTRIBUTING.md file
