When installing a plugin, if it contains a `PulumiPlugin.yaml` file with a `runtime` value of `nodejs` or `python`, install dependencies for the plugin. For Node.js, `npm install` is run (or `yarn install` if `PULUMI_PREFER_YARN` is set). For Python, a virtual environment is created and deps installed into it.
