Translation bubble is not shown on nightly builds

[yrliou]

Description

When visits a page in a different locale on nightly, translation bubble is not shown automatically.
This is because we don't have google API key configured, so the translate flow is not triggered.

Steps to Reproduce

1. Visit https://www.deutschland.de/de/topic/wissen/school-of-games-ausbildung-zum-spieleentwickler or any pages not in your default locale.

Actual result:

No translation bubble prompt in the url bar.

Expected result:

Should have a translation bubble prompt in the url bar.

Reproduces how often:

Every time.
