update gatsby-source-drupal to match new json api endpoint

[tcfunk]

Drupal JSON API has changed their endpoint base from api to jsonapi. This updates gatsby-source-drupal to match this, and allows override to old endpoint if necessary.

See https://www.drupal.org/docs/8/modules/json-api/api-overview

Looks great, thanks!

Could you document this in the README e.g. what version of json-api made the change + how to set the apibase?

[tcfunk]

Yeah, sure. Not sure about the jsonapi version but I can do some digging.

[tcfunk]

Added some documentation, let me know if it's what you're looking for or if you have some further suggestions. Thanks!

[tcfunk]

Just pinging this in case it got lost. Let me know if there's more I can do to get the change accepted, I could really use the update for my current project :)

[KyleAMathews]

Really sorry about the slow merge — been crazy busy last week or so. Merging and publishing! Hopefully you can share the project once it's done! Would love to see what you build :-)

[tcfunk]

No worries, I can identify with having a crazy week :) Thanks for the merge!
