feature request: Terraform syntax highlighting

[kamaradski]

Not a biggy, but was missing this in the list when sending some terraform code to another user

Unfortunately, it's not super straightforward due to the way syntect works. But if I come across a larger syntax set than what's provided by Zola, I'll definitely update it.

To be really fair the syntax highlighting is a bonus feature for me, so it's fine :) don't waste to much time on it.
