Add useful VS Code snippets

[JordanMartinez]

Context

Design Pattern
Enhancement = a new idea that can be documented/filed

Body

These are some snippets I've used over time:

purescript.json

{
	// Place your snippets for purescript here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	//
	// See https://github.com/microsoft/vscode/blob/main/src/vs/editor/contrib/snippet/browser/snippet.md
	// for syntax and transforms
	//
	// Example:
	// "Print to console": {
	// 	"prefix": "log",
	// 	"body": [
	// 		"console.log('$1');",
	// 		"$2"
	// 	],
	// 	"description": "Log output to console"
	// }
