Data type and conversions are stricter for BQ sinks

From https://github.com/apache/beam/pull/17404, it seems like the timestamp conversion has been made stricter, such that the pipeline only accepts timestamps in the form “2022-05-09T18:04:59Z”.

Here are some formats that previously worked, but seem to no longer be accepted:

“2022-05-09 18:04:59”

“2022-05-09T18:04:59”

“2022-05-09T18:04:59.739-07:00”

Also from the same pull request, it seems to no longer accept integers in fields marked as floats

Unexpected value :0, type: class java.lang.Integer. Table field name: a, type: FLOAT64

Are these the desired behaviors? It’s different from the behavior I’ve observed when using the Streaming Inserts method.
