Test Container from DB URL `r2dbc:tc:` not working

[pontus-eliason]

When using test containers and the path to the database is specified using the spring.r2dbc.url property using the format of r2dbc:tc:postgresql:///database a database container will be automatically created.

The problem is that this project does not recognize this format and does not properly replace the parts of the database url from r2dbc to jdbc, or figure out the actual host and address of the container running the database.

See TestContainer documentation for how this works using Spring Boot.
