chore(renovate): stop ignoring test/e2e/internal/tests/** (#996)

ignorePaths still had '**/tests/**' left over from the recommended
preset, even though a comment right above documents removing
'**/test/**' specifically to let renovate scan test/e2e for emulator
image dependencies. Every e2e Ginkgo package lives under
test/e2e/internal/tests/**, so the plural pattern was silently excluding
all of them; any image pinned by digest in those packages (e.g. minio,
aws-cli) was never going to get a bump PR.

No other tracked path in the repo matches '**/tests/**' once
node_modules is excluded by its own rule, so this narrows nothing else.
