Remove use of index-provider option (#1096)
Supplying the index-provider option will no longer have any effect, and a user should not specify it. From 5.26 using the index-provider option will generate a warning. The index-provider has never controlled index behaviour in the 5.x series, and the latest provider will always be the best one. --------- Co-authored-by: Jens Pryce-Åklundh <[email protected]>

==== Creating constraints with an index provider

Because property uniqueness and key constraints have backing indexes, an index provider can be provided when creating these constraints using the `OPTIONS` clause and the `indexProvider` option.
