Expected behavior
Return the version of migrate-mongo, e.g. 9.0.0

Same error when I run migrate-mongo up with v10 globally installed in a Docker container with image node:14-alpine. The repository has mongoose@5.12.12 installed which also requires mongodb@3.6.8, defined in the package-lock.json file. I can see it locally for the repository in node_modules/mongodb.

EDIT: Seems that v10 (e4d9446) of this package now requires MongoDB 4 or 5 as a peer dependency. With Node 14 peer dependencies aren't automatically installed so it so it cannot find a mongodb installation which matches this condition since I'm still using mongodb@3.6.8.
