Code formatting

[geekyme]

As we get more contributions to this repo, I think its best to have automated code formatting. Prettier is a good option.

See this link for tips on how to configure it with go templates (the syntax that hugo use) https://discourse.gohugo.io/t/hugo-and-prettier/22596

@geekyme I have added the following configuration should I create a PR?
{
"useTabs": false,
"trailingComma": "es5",
"tabWidth": 4,
"semi": false,
"singleQuote": true,
"overrides": [
{
"files": ["*.html"],
"options": {
"parser": "go-template"
}
}
]
}

Sure please go ahead! Thank you! We'll need to probably have some git commit hooks as well.
