Hello everyone !

Is your feature request related to a problem? Please describe.
I was searching the documentation to install Let's Encrypt certificates on XO(A). I knew this doc exists because I did implement LE certs several months ago on my XOA.
I didn't find the "How-to" on the official doc (https://xen-orchestra.com/docs/), but I found how to implement LE on some other links, like here and here

Describe the solution you'd like
I would like to add the "How-to" in the official documentation. However, I don't really know where to put this. Maybe below this https://xen-orchestra.com/docs/configuration.html#https-and-certificates or elsewhere ?

Describe alternatives you've considered
I think this need to be in the official doc, for futures references, and it's more easily to retrieve the How-to in the official doc then on the blog or GitHub ^^

Additional context
Thank you for all your hard work 🚀
