yarn create gatsby uses npm to install gatsby instead of yarn

When I run yarn create gatsby, it asks me the usual questions, but then it uses npm to install gatsby and its dependencies. Is there a way to use yarn instead, or has that not been implemented yet?

Edit: I did some investigation in create-gatsby's source and the part in question is this:

gatsby/packages/create-gatsby/src/init-starter.ts

Lines 12 to 31 in bfce533

	const packageManagerConfigKey = `cli.packageManager`
	export const getPackageManager = (
	npmConfigUserAgent?: string
	): PackageManager => {
	const configStore = getConfigStore()
	const actualPackageManager = configStore.get(packageManagerConfigKey)
	if (actualPackageManager) {
	return actualPackageManager
	}
	if (npmConfigUserAgent?.includes(`yarn`)) {
	configStore.set(packageManagerConfigKey, `yarn`)
	return `yarn`
	}
	configStore.set(packageManagerConfigKey, `npm`)
	return `npm`
	}

So... I have to set something in a config file? I checked the .npmrc options and it didn't mention anything about cli.packageManager...

Did more digging, found out the config file I needed to change: https://github.com/gatsbyjs/gatsby/blob/master/docs/docs/glossary/yarn.md#using-yarn-as-your-gatsby-package-manager
