Revert: asset path

[Deleplace]

Fixes #98

• Revert "read index.html using absolute path (Read index.html using absolute path #96)"
• Revert "read assets/ using absolute path (Read assets/ using absolute path #97)"

I could confirm this code (after revert) works correctly:

• locally

% go run . 

• in Docker:

docker build -t cloud-run-hello-fix98 .
docker run -ePORT=8080 -p8080:8080 cloud-run-hello-fix98

See also #99, which would avoid this ambiguity altogether

Hi Valentin, thanks for catching this. The purpose of PR #96 and #97 was to fix the broken deployment of the placeholder image to Cloud Run with automatic base image update (private preview feature).

Created PR #102 to cover all use cases.

It looks like this PR's change was reimplemented and merged in #102. Are we good to close this one?
