Compatibility Check Error

[jtoar]

Hey @ahaywood, I haven't looked at the docs yet but there's a small regression here in that we no longer handle the case when yarn is below the required version:

I set yarn to 1.14.0 via

yarn set version 1.14.0 # for the framework
corepack prepare yarn@1.14.0 --activate # for my system

The errorMessages const handled the yarn error messaging:

redwood/packages/create-redwood-app/src/create-redwood-app.js

Lines 85 to 99 in 7856e0e

	const errorMessages = [
	{
	type: 'node',
	failedCompatibilityCheck: foundNodeVersionIsLessThanRequired,
	},
	{
	type: 'yarn',
	failedCompatibilityCheck: foundYarnVersionIsLessThanRequired,
	},
	]
	.filter(({ failedCompatibilityCheck }) => failedCompatibilityCheck)
	.map(
	({ type }) =>
	` ${type} ${checksData[type].wanted.range} required; found ${checksData[type].version.version}`
	)

We probably just need another conditional somewhere to show the right error.

@jtoar I added an additional conditional to check for the user's current version of yarn. I also created a doc specifically for yarn. This is ready for another review.

@ahaywood the code changes work great! Just reviewed the docs and they look good too, just left a few minor comments. We just need to get rid of the lint error by removing the unused variable errorMessages variables and CI should pass.

@jtoar Made updates and ready for your review (again)
