Search field:number on stackoverflow dataset returns no document with dynamic index config

[fmassot]

Quickwit version: main branch

answerId:"7" or answerId:7 queries do not return documents.

type:answer returns documents.

Here is the emitted tantivy query:

BooleanQuery { subqueries: [(Should, TermQuery(Term(field=3, type=Json, path=answerId, type=U64, 20431))), (Should, TermQuery(Term(field=3, type=Json, path=answerId, type=Str, "20431")))] }

I think we should emit TermQuery(Term(field=3, type=Json, path=answerId, type=I64, 20431), not U64.
