> Add support for [REGEXP_REPLACE
> |https://cloud.google.com/bigquery/docs/reference/standard-sql/string_functions#regexp_replace]
> function from BigQuery.
> *{{REGEXP_REPLACE(value, regexp, replacement)}}*
> Returns a STRING where all substrings of {{value}} that match regular
> expression {{regexp}} are replaced with {{{}replacement{}}}.
> backslashed-escaped digits (\1 to \9) can be used within the {{replacement}}
> argument to insert text matching the corresponding parenthesized group in the
> {{regexp}} pattern.
> Example (added one space between \ \ to override md formatting):
> {{SELECT REGEXP_REPLACE("abc'", "b(.)", "X\ \1") as result;}}
> |result|
> |aXc|
