I couldn't find anything public. :-(

Here there are rules for 3 file types only:
https://github.com/godaddy/yara-rules/tree/master/utility

But keep in mind that Yara as a module called "magic" that contains the
database used in libmagic (by "file" UNIX command for example):
https://yara.readthedocs.io/en/v3.5.0/modules/magic.html - this should have
enough signatures for most cases.
