Remove Inter as an example of a Google Font

[flexagoon]

According to Inter's README, it should not be installed from Google Fonts unless you have no other choice - that version is very outdated. Currently, the documentation for BlueBuild's fonts module shows Inter as an example of a font that can be installed from Google Fonts. Instead, it should be given as an example of a font installed from a custom URL.

Inter can be installed via dnf with the rsms-inter-fonts package (just adding for a possible solution for installing fonts that are in the distro repos)
