Fixes according latest upgrades

* Add `--add-opens` to `asciidoctor` Gradle task to avoid compilation warning
* Upgrade to Kotlin `1.6.10` and modify its Gradle task respective
* Add empty impl for new `AnnotationMetadataAdapter.getDeclaredMethods()`
* Parse HTTP methods to new `String methodNames` property of the `RequestMapping`
since `HttpMethod` is not an `enum` anymore.
* Ignore JDBC tests which rely on a map property resolution: the `[]` placeholder
is not handled in the latest SF anymore.
* Fix `WebFluxInboundEndpoint` for deprecations
