Add support for Couchbase testcontainers and Docker compose

[hantsy]

I tried to generate a Spring boot with following config in the start.spring.io.

• Maven
• java 21
• Dependencies: Reactive Web, Spring Data Couchbase Reactive, Testcontainers

In the generated files, the TestcontainersConfiguration is an empty class like this.

@TestConfiguration(proxyBeanMethods = false)
class TestcontainersConfiguration {

}

I guess you're asking for code generation support for the CouchbaseContainer?

[hantsy]

Yeah, for other dbs it generates the testcontainerConfig with a Testcontainers docker container bean correctly.

A strange thing about couchbase is when I added the CouchbaseServer bean manually, I found it depends on spring.data.couchbase.bucketName property. Without this property, the tests will be failed with a Repository not found when running the repository tests with a @DataCouchbaseTest.
