be more explicit in gitignore

[xenoterracide]

I have a global ~/.gitignore which ignores archives (generally sensible)

# Archives
# https://github.com/github/gitignore/blob/master/Global/Archives.gitignore
# It's better to unpack these files and commit the raw source because
# git has its own built in compression methods.
*.7z
*.jar
*.rar
*.zip
*.gz
*.gzip
*.tgz
*.bzip
*.bzip2
*.bz2
*.xz
*.lzma
*.cab
*.xar
*.zst

# Packing-only formats
*.iso
*.tar

# Package management formats
*.dmg
*.xpi
*.gem
*.egg
*.deb
*.rpm
*.msi
*.msm
*.msp
*.txz

I believe that if these sensible rules were added to the repo the same problem would exist.

unfortunately, when combined with a yadm ignore file in a specific repo, it also excludes the zips to be committed, updating the suggested yarn rule from simply the directory seems much more sensible since you wouldn't want a zip file in an arbitrary directory.

!.yarn/cache/*.zip

alternatives to this also exist (e.g. you can omit the extension and just do a glob), but being more specific helps
