There is a diff when running code generation for google-cloud-spanner. I didn't check all packages. Please can you run generation for all the packages that were changed so there is no diff?

I'm going to switch this to draft but please mark it ready for review once the generated code has been updated

Revert the changes to .librarian/generator-input/client-post-processing/bigtable-integration.yaml and .librarian/generator-input/client-post-processing/spanner-integration.yaml since code generation will happen in a future PR

I reverted them for now. But does this mean we'll have to come back and finish this after the next generation?

Could we also apply the generated changes for these libraries early here, and prevent the diff that way?
