Mono fonts contains ligatures
#### 🎯 Subject of the issue

After reading the following:

> By the Nerd Font policy, the variant with the 'Mono' suffix is not supposed to have any ligatures. Use the non-Mono variants to have ligatures.

I downloaded several Mono variants from the `patched-fonts` directory only to find that *did* contain ligatures. This was both surprising and a bit problematic since my terminal doesn't allow for turning of ligatures explicitly.

Is the policy inaccurate or are several of the patched fonts wrong?
