Fix statik directory structure

[IsaacPD]

Fixes: #5253

Description
For some reason the way that I had generated the statik file in #5157 for the metrics credentials conflicted with the existing method that creats the statik file structure. This resulted in calls to skaffold schema get and skaffold credits returning file not found if running skaffold built from master with all the licenses and etc. being built in.

In order to fix this I followed similarly to the previous statik generation and moved it into the temp directory that ultimately gets exported to cmd/skaffold/app/cmd/statik/statik.go

Fortunately this bug has not made it into a release so we can fix this and hopefully no one will notice 😅. If not fixed this would also ultimately affect the build release script since it relies on skaffold credits

RUN skaffold credits -d /THIRD_PARTY_NOTICES

skaffold credits and skaffold schema get work
