Use inner query for equals/hashCode() in SourceConfirmedTextQuery (#134451)
We were using a valueFetcher lambda and an Analyzer as part of the equals and hashCode implementations which could easily compare as unequal for logically equal queries. We can safely just use the inner query for comparisons and hashcodes as the results of the outer query are identical to running the inner query against a shard with indexed positions. Fixes #134432
