would be nice if there was an installable version

You seem to list it as a benefit that there is no installation required and you can just copy/paste what you need. However, while this is certainly an option and why not, it could be even more convenient if you could install it with yarn and then add it globally to your main.js file, or import individual components, as you wish. Then you could do things like <vt-modal>. Similar to how https://github.com/bootstrap-vue/bootstrap-vue works.

And then if you do any updates to components then we can pull in the updates by doing a simple yarn/npm update

I personally would appreciate this option and would use that and find it more convenient. It may help your package receive more exposure as well. Nowadays I don't think there are many libraries on Github/NPM that require you to copy/paste things manually
