Fix typo in Python snapshot generation workflow

Fixes typo in wrong secret key

Splitted out from: #6683

[ask-bonk]

The change is a single-character fix: renaming GOOGLESOURCE_COOKE to GOOGLESOURCE_COOKIE — correcting a typo in a secret key name passed to a reusable workflow. The right-hand side (${{ secrets.GOOGLESOURCE_COOKIE }}) was already correct, but the left-hand side (the key the called workflow receives) was misspelled, which would cause the called workflow to not receive the secret under its expected name.

This is a clear, correct, minimal fix. No code, no API changes, no backward compatibility concerns.
