Support for Eleventy 1.0

[John Riviello]

I just tried upgrading our existing Eleventy project to Eleventy 1.0 Beta and ran into some errors due to eleventy-plugin-i18n currently requiring Eleventy prior to v1.0.0:

Ah cool, I haven't had a chance to play with the 1.0 beta yet. Thanks for flagging, @JohnRiv.

A similar issue came up with the move from 0.11.x to 0.12. While we worked around that with a simple deps update (PR #13), it's possible there are breaking changes here.

Will need to be tested against v1.0 to confirm all still works as expected. Won't have the chance to get around to this right away. Open to PRs in the meantime 👍

OK great, thanks @adamduncan. We did a quick test at work and things looked good with updating the peerDependencies. One of us can put up a PR.

FYI, looking at 11ty/eleventy#2001, we'll have to do something similar to the change in other eleventy-plugins to make this work

Made an update to get eleventy-plugin-i18n working with eleventy 1.0.0. I didn't notice anything breaking in our project which uses this as a dependency. I did run the sample script on both your master branch and mine, and saw the same errors on both branches.
