GH-8692 Add createIndexes to MongoDbMessageStore

Fixes https://github.com/spring-projects/spring-integration/issues/8692

* Added `createIndexes` in `AbstractConfigurableMongoDbMessageStore`
* Added Javadoc for `setCreateIndex()` method
* Removed `afterPropertiesSet()` in `MongoDbChannelMessageStore` and update `whats-new.adoc` and `mongodb.adoc` files

**Cherry-pick to `6.1.x` & `6.0.x`**

# Conflicts:
#	src/reference/antora/modules/ROOT/pages/whats-new.adoc
#	src/reference/asciidoc/mongodb.adoc
