multi: use fillPlaceHolders in CountActions

This commits ensures that the `CountActions` function in the `sqlc` &
`sqlcmig6` packages utilizes the `fillPlaceHolders` function to properly
handle SQL query placeholders.

This ensures that the function works correctly on `Postgres` backends
when it contains ? placeholders instead of positional ones (e.g., $1).
