Update samples to use Spring Cloud Azure 6.0.0-beta.1

[moarychan]

This PR is to support the Spring Cloud Azure 6.0.0-beta.1 based on Spring Boot 3.0.0-M4. Exclude some samples because the below reasons:

• storage-blob-native Spring Native is not supported since Spring Boot 3
• spring-petclinic-microservices Need to refactor the code since the spring-cloud-dependencies 2022.0.0-M4 does not include the spring-cloud-netflix-dependencies
• appconfiguration/azure-spring-cloud-* These samples may be included in the second millestone version of Spring Cloud Azure.
• cosmos/spring-cloud-azure-starter-data-cosmos/, cosmos/azure-spring-data-cosmos/, cloudfoundry/azure-cloud-foundry-service-sample Spring Data Cosmos samples may be included in the second millestone version of Spring Cloud Azure.
• keyvault/azure-spring-boot-starter-keyvault-certificates/* The samples of keyvault-certificates-xx can running with Spring Boot 3, but the JCA samples of run-with-command-line-xxx will fail with exception java.security.NoSuchAlgorithmException: SHA MessageDigest not available, so these samples should be excluded too.
