chore(e2e): restrict git ceiling directory for actor push (apify#3467)

The new `apify-cli` uses `git ls-files` for file collection, which walks
up to the repo root and picks up the root `.gitignore` rule
`test/e2e/**/packages` — silently excluding the copied crawlee packages
from the upload and breaking Docker builds on the platform.
Fix: set `GIT_CEILING_DIRECTORIES` when calling `apify push` so git
doesn't traverse past the actor directory.
