Console warn "Duplicate field names in DataFrame: message" seen on a Grafana instance with 0.4.0-beta.2 version:

I did not reproduce it locally. I tested a Grafana 10.3.3 with Quickwit 0.4.0-beta.2 installed.

Likely culprit : https://github.com/quickwit-oss/quickwit-datasource/blob/main/src/datasource.ts#L773

If we're going to modify the dataFrame, we should probably prefix our fields to avoid collisions.

$qw_${field.name}?

@ddelemeny sounds good
