Add minimal template

[jonathantneal]

Changes

This adds a new minimal template to create-astro.

• Minimal includes no framework.
• Minimal includes no components.
• Minimal includes no frontmatter in src/pages/index.astro.
• Minimal includes astro.config.js & snowpack.config.js configurations to (hopefully) disable any default plugins or renderers.
• Minimal uses "type": "module". (because it’s available in the oldest Node LTS at the time of this writing).
• Minimal uses 1 tab instead of 4 spaces.

Testing

I was unable to test this. I encountered a strange error running npm run test:templates:

For another PR, but I really want to make this the default soon, so this file wouldn't be necessary either.

[jonathantneal]

I may be wrong, but an empty array might trigger their installation anyway. Therefore, with your approval, I’d like to remove this file as well, and move my +1 over to your suggestion that "no renderers" be the default.

[natemoo-re]

I do think it's about time to do that, but not in the scope of this PR. Let's leave this file for now.

A todo item for me is to add some warnings about the upcoming behavior change to the next version so we can make the switch in the version after that.

[jonathantneal]

If an empty array doesn’t currently limit the renderers, should I still keep this line? Not sure if I’m to:

• A. Keep the line. It has an effect.
• B. Remove the line. It has no effect.
• C. Remove the file, because the line has no effect.

If the line has an effect, then I would vote A, but if it has no effect then I’m on the fence between B and C.

[jonathantneal]

Thanks for the thoughtful dialog, @natemoo-re! Thanks for making me smile, @jasikpark!

Following your suggestion, I’ve removed snowpack.config.js in dfc2525. I’ve also left some feedback that I hope will help us resolve our remaining questions.

[jasikpark]

Adjacent to this PR, it'd be nice to have a setup that works similar to create-react-app that will setup eslint and various linters for you + a super-minimal scaffolding.. similar also to hugo new site

LGTM! @natemoo-re do you have any more feedback or can this be merged?

[natemoo-re]

@jasikpark LGTM! Feel free to merge.
