Explicitly pass --domain to make-pot

The default value for `--domain` is the project slug when `Text Domain` is not specified in the main plugin or theme file. Explicitly passing the text domain avoids the scenario where someone checks the repository out in a folder with a custom name.

Also adds `vendor` and `node_modules` to the `--exclude` flag.
