Subject: [PATCH] fix(template): cast the update_mask argument to text[]

The UPDATE queries test each column with
'<column>' = any(sqlc.arg(update_mask)). Some sqlc plugins (sqlc-gen-sqlx,
used by grpc-rust-template) cannot infer the parameter's type there and
need the explicit text[] cast; Go's pgx accepts it either way. Casting in
the template lets every downstream template use the generated queries
unchanged instead of patching them.
