Google Sheets Source reorders columns

## Tell us about the problem you're trying to solve
I am using the Google Sheets connector as a source.

The columns in the source are ordered in a different way than the destination output. As a user, this is confusing to me because I would expect the destination output to mimic the column order, rather than reordering by logic I don't see. With a larger number of columns, it would be harder to debug quickly whether all the columns have successfully passed through Airbyte and no data is missing.

Data in BigQuery:

## Describe the solution you’d like
The ordering of the columns in the destination to match the order of the columns in the source.
