[bitnami/spring-cloud-dataflow] Modify version test for spring-cloud-dataflow

[migruiz4]

Description of the change

Modifies version test for spring-cloud-dataflow, which fails in the latest version 2.11.0

The test consists of:

• Uncompressing the jar file in a temporary directory
• Checks the content of ./BOOT-INF/classes/application.yml which should look like this:

info:
  app:
    name: "spring-cloud-dataflow-server"
    description: "Spring Cloud Data Flow Server"
    version: "2.11.0"
spring:
  jpa:
    hibernate:
      ddl-auto: none
