The enabled by default statement made sense when the developer was supposed to disable flow in order to use ts. Both those statements in there create some confusion about it in my opinion.

* Improved language used in code blocks.

As part of the latest babel-plugin-macros [2.4.5 release](https://github.com/kentcdodds/babel-plugin-macros/releases/tag/v2.4.5), there was a small fix that went in that fixes a [bug](https://github.com/kentcdodds/babel-plugin-macros/pull/100) specifying the `babelMacros` entry in `package.json` no longer working. This patch version increase should remedy the issue and allow specifying babel macro configuration in the `package.json` file again (as stated in the [user docs](https://github.com/kentcdodds/babel-plugin-macros/blob/master/other/docs/user.md#config-experimental) of babel-plugin-macros)
