Explicitly truncate updated_at and created_at

[ericaporter]

We need to explicitly truncate updated_at and created_at timestamps to milliseconds to be able to compare checksums between production db tables and Dataform

The where clause here:

dfe-analytics/lib/dfe/analytics/shared/checksum_query_components.rb

Line 5 in 8001546

def build_where_clause(order_column, table_name_sanitized, checksum_calculated_at_sanitized)

Which is used to filter out anything before checksum_calculated_at still uses microseconds precision for the order column. This will be different in BQ as it doesn't have microseconds. We just need to make this consistent also between dfe-analytics and BQ.

Good point. It's easy enough for me to change that in dfe-analytics-dataform if @ericaporter you are happy to change in dfe-analytics as well?
