BigQuery: Move some keywords to unreserved

[tunetheweb]

Brief summary of the change made

As part of #2989 two new keywords were added to BigQuery as Reserved Words, but they should have been added as Unreserved words and they are now causing some of my queries to fail.

FYI @dmohns

Are there any other side effects of this change that we should be aware of?

Nope
