Updating an existing table (e.g. adding a column) is not reflected in the metadata #150
Description
Hello 👋 Thank you for this lovely project
Somehow similar to #81, I'm updating a table (adding a column using the code in https://cloud.google.com/bigquery/docs/managing-table-schemas#add_an_empty_column) but it's not reflected in the table metadata.
I use client.Dataset(datasetID).Table(tableName).Metadata(ctx) to read the metadata after updating the table.
Is that expected?
This issue is a bit different than #81 as I don't get an error on the update call.
I can prepare a reproduction repo if that helps
It does work on a real BigQuery dataset, with a delay in schema propagation which is expected
