[v2] provide non-traspiled version of default-html.js to copy from

[ng-hai]

Description

I want to customize html.js but the default-html.js file is transpiled to ES5 by default.

Steps to reproduce

Install all the dependencies from package.json using yarn, run gatsby develop, it will generate .cache folder.

Copy the default-html.js in .cache folder to src/html.js

cp .cache/default-html.js src/html.js

Expected result

The content of default-html.js should be ES6, not be transpiled by default.

Actual result

The content of html.js is not ES6

Right - this was one of the changes in v2.

Need to figure out nice way of supplying default-html.js to copy from to release now. For now You can grab source version from here https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/cache-dir/default-html.js .

Would it be possible to just dump a comment with a link to the source, or maybe a comment with a note and the full untranspiled file for people to copy out?

@deltaskelta #6183 will fix this this (revert to use use non transpiled version of files in cache-dir)
