Google Cloud CLI upgrade shows SyntaxWarning: invalid escape sequence

Today I upgraded Google Cloud SDK to the latest version 509.0.0.0 on Debian 12 and I noticed:

Setting up google-cloud-cli (509.0.0-0) ...

Can I safely ignore these syntax warnings?

Or do you recommend to downgrade to the previous version?
