Use local fonts instead of Google

[meirroth]

I assume most if not a lot of people using umami are doing so to avoid Google because of privacy concerns. that's why I suggest adding a Environment variable like: LOCAL_FONTS for example, that will load local hosted fonts instead of from Google servers.
Or removing google fonts entirely and host the fonts locally by default.

I am willing to create a pull request if this is something you accept.

Big supporter of this! Google Fonts has relatively aggressive caching headers, caching for about a year, so the privacy implications are mild, but I'd still favour including them.
