Gatsby: Documentation about caching javascripts assets needs an update

[abumalick]

Description

Documentation about caching javascript is outdated:

https://www.gatsbyjs.org/docs/caching/#javascript

Other files e.g. JavaScript files are not (yet) cachable. Gatsby v1 is using webpack 1 which doesn’t make it possible to produce paths tied directly to the content of the file. Gatsby v2 will ship with webpack 4 which will make possible long-term caching of our JavaScript files.

The cache-control header should be cache-control: public, max-age=0, must-revalidate

Steps to reproduce

mmmh, visit the documentation link https://www.gatsbyjs.org/docs/caching/#javascript

Expected result

have the documentation about caching javascript assets for gastsby v2

Actual result

The documentation describe what to do for gatsby v1

Environment

We also need to update gatsby-plugin-netlify as part of this change https://github.com/gatsbyjs/gatsby/blob/6951db0864190015d05d763980e34424db9fbc39/packages/gatsby-plugin-netlify/src/constants.js#L28
