Initial release errors (TypeError versions.filter)

Description

Run yarn -s dripip preview-or-pr
    TypeError: versions.filter is not a function
Error: Process completed with exit code 1.

I believe this error is being thrown because this code is erroring:

dripip/src/utils/pr-release.ts

Lines 103 to 108 in 2e8d2cb

	function getPackageVersions(packageName: string): string[] {
	// todo do http request instead of cli spawn for perf
	const result = spawnSync('npm', ['show', packageName, 'versions', '--json'])
	if (result.error) throw result.error
	return JSON.parse(result.stdout)
	}

Repro Steps/Link

• Create a new package repo
• Open a pull request to add dripip workflow
• Errors fetching package versions since the package doesn't exist yet

For now, I worked around this by manually publishing, this then worked as expected.
