fix automatic to explicit index parameter conversion

[JanezStupar]

Under the hood sql_crdt operates with explicit parameter indices (?1, ?2. ?3,... ) which leads to conflicts whenever a client uses implicit parameter indexing (?, ?, ?,... ).

This PR ensures parameter conversion from implicit to explicit.

Thanks, Janez!
It seems the format check failed, would you mind having a look? Otherwise I can fix it on my end.

Hey Daniel, that is a bit awkward, but running dart format on my local machine changes nothing, both with dart 3.7.2 and 3.8.0, I see that github ran 3.7.3?

I tried to run the workflow locally but got stuck in networking stuff (it expects ipv6, which doesn't work in my network because of reasons) so at this point I would be extremely grateful if you could have a look at this.

I think I see the problem - the GitHub runner seems to be running a more recent version of Dart than the one shipped with Flutter.

I'm having the same issue in other projects. Let's just ignore it for now.

Thanks again for your effort!
