BigQuery supports named arguments in several functions.
https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-reference#named_arguments

Named arguments are sometimes used in JSON functions and Geography functions.

Reading at the PostgreSQL implementation, it is not difficult to just add it to operators, so I'll try to PR it.
If the operator should work only in the function call, reject it.

Thanks for the PR. I've release sql-formatter 12.2.1 with the fix. 💯
