* Custom formatters will need to migrate
* `json` formatter is deprecated and will be removed in next major release. Custom formatters should migrate to use the `message` formatter, or the [standalone JSON formatter](https://github.com/cucumber/cucumber/tree/master/json-formatter) as a stopgap.
* Remove long-deprecated `typeName` from options object for `defineParameterType` in favour of `name`
* Custom formatters are no longer loaded relative to the current directory unless it begins with a dot (e.g. `--format=./relpath/to/formatter`)

This should be using createRequire to run the require from the cwd

Yeah that seems a fair point, although per the docs:

module.createRequire(filename)#

Added in: v12.2.0

Given we're still supporting Node 10 for the time being (its EOL is April 2021), could use https://github.com/sindresorhus/import-cwd instead.

I'd suggest using https://yarnpkg.com/package/create-require as it will use the node builtins when it can, so createRequire on node >= 12.2 createRequireFromPath on node >= 10.12, then a polyfil for the rest which is much better

Should actually use it for both branches here, which simplifies the logic and has the same end result
