Revert "cros-sommelier-config: revbump the package"

This reverts commit 339cae00950eb68ec67ae132f1b6814672f55414.

Reason for revert: The same fix has also been applied inside sommelier itself for M91 and M92, and testing shows that this is effective. As this config file hasn't been pushed out yet, revert the change here.

Original change's description:
> cros-sommelier-config: revbump the package
>
> The last few changes to this package did not revbump the package, so
> people won't upgrade when they `apt upgrade`.
>
> BUG=b:180731892
> TEST=n/a
