I'm comfortable with this, @pirog does it pass your smell test? Know it seems a little edge case-y but want to encourage people to be making plugins obviously, no matter if a keyword attribute is available in their code repository's API output :)

@Xilonz could you resolve the code linting errors and add documentation.

Would be ideal to have a test, could probably just target a repo that's an NPM package (but not a Lando plugin) and have it try to download that with the --force option.

@reynoldsalec Just noticed that package installs from tar.gz's are supported as well (its not in the docs tough). Is that planned to stay as a feature? If so, there's probably enough methods available to install a package to suit everyone's needs.

The only disadvantage I see is that when using tar.gz (and .git?), is that it has to be a build.
