Upgrading pretty-format bumped the minimum Node version to 10.14.2

[exogen]

👋 Hello! I noticed that in between v7.2.2 and v7.3.0, there was a major upgrade to pretty-format. Unfortunately, this changes the minimum Node version, so it's possible to minor bump @testing-library/dom and not work with the same Node anymore.

• @testing-library/dom version: v7.4.0
• Testing Framework and version: jest@24.9.0
• DOM Environment: jsdom@11.12.0

What you did:

$ yarn

What happened:

$ yarn
error pretty-format@26.0.1: The engine "node" is incompatible with this module. Expected version ">= 10.14.2". Got "10.13.0"
error Found incompatible module.

Problem description:

Due to the pretty-format major version bump in #546, the minimum Node version changed to 10.14.2 in between @testing-library/dom v7.2.2 and v7.3.0.

Given the value in engines and relatively recent #480, it seems intentional to support older Node 10 versions. (For reference, I ran into this because my current client happens to use images containing v10.13.0 for our deploys.)

Suggested solution:

Downgrade pretty-format back to v25, or update this package's stated support.

I think we'll probably need to downgrade as suggested and then we can upgrade in the next major version bump.

A PR is welcome.
