Add a VS Code snippet config for creating new BCD files.

[connorshea]

I'm not sure if this is particularly useful, but I figured I'd try it anyway :) This makes it really easy to create a new BCD file. It'll show up whenever you type bcd in a JSON file in this repository.

NOTE: You'll need v1.28 (just came out today) for this, otherwise project-level snippets won't work.

Here's an example video

I created this with help from https://snippet-generator.app

It may also be worth adding a snippet for a file with a subfeature, for convenience's sake.

I used this when creating the hanging-punctuation PR (#2950), and I think it's worth noting that the snippet doesn't work quite right for CSS because it doesn't suggest the subcategories, e.g. properties, at-rules, selectors, types. The same is true of JavaScript. I'm not sure if there should be snippets for each type of BCD file or if this is fine as-is.

Thanks for this @connorshea, I just tested it and it's a nice enhancement. It might not be perfect for every case, but it's a nice template to start from.
I have a suggestion for the status block, but otherwise this is good to go for me.

Can we make this ${6|false,true|}" ?
If you don't tab through until here, it is set to true by default and deprecated: true isn't typical most of the time.

I'd also suggest to make this false,true
