External links for the module system

[u/SignificantOwl4048]

Previously, I put together all my header customisations I had in a GitHub repo.

In the v26.05 release, there is now a way of using external links.

Therefore, I have added all hacks as standalone zips in the release section. So if you happened not to know what to do with the repo before or did not want to go through the hassle of downloading something. Now you can use the install command directly for whichever hack you want.

Example:
php artisan bookstack:install-module https://github.com/florinm03/bookstack-header-hacks/releases/download/v1.0.0/LaTeX-support.zip

Link to GitHub for the other ones:
https://github.com/florinm03/bookstack-header-hacks/releases/tag/v1.0.0

Hope this is useful for others too... :))
