YAML validation fails for imported repo with `imported_repo: true`

[fschrempf]

I'm trying to setup the "Development in Imported Repos" feature as documented here: https://github.com/jdoiro3/mkdocs-multirepo-plugin#%CE%B2-development-in-imported-repos-beta.

Unfortunately I'm always getting the following exception. I'm using the latest release v0.6.1.

This feature is still not tested and in beta. I (or someone else) will need to make time to work on this feature (and this issue).
