update cache helper to skip to a "neutral" folder to check remote from
works around an issue where .git can get confused when checking a remote for its hash, and where the below command fails on corrupted .git folders. This happens to me locally when building lambda_container, as some .git folder abomination gets put into the context when building. should probably review what's in our .dockerignore's as well.
```
git ls-remote https://github.com/rive-app/skia rive
fatal: not a git repository: /app/submodules/rive-recorder/submodules/rive-cpp/../../../../.git/modules/submodules/rive-recorder/modules/submodules/rive-cpp
```
