skaffold schema get and skaffold credits don't work when secret credentials exist

[IsaacPD]

skaffold credits and skaffold schema get fail and don't work as intended when a metrics credential secret is provided during the make process. Basically a repeat of #3428

Expected behavior

skaffold schema get skaffold/v1 prints the schema for skaffold/v1

Actual behavior

skaffold schema get skaffold/v1 prints

schema "skaffold/v1" not found: file does not exist

Information

This should only affect skaffold built after #5157

Steps to reproduce the behavior

1. export SECRET=~/path/to/some/not-empty/directory
2. make clean install
3. Ensure generating statik for secret shows during make
4. skaffold schema get skaffold/v1

Strangely skaffold credits -d dir when working also doesn't write directly to dir but instead to dir/.. as can be seen here

skaffold/cmd/skaffold/app/cmd/credits/export.go

Line 44 in dafb415

newPath := path.Join(Path, "..", filePath)

So when running skaffold credits -d ~/credits the output is no different than if running cd ~ && skaffold credits
