[SELC-8117] Upgrade to Spring Boot 3.3.0

[gaetano-miglionico]

List of Changes

• Updated the starter POM to 0.3.2 and selfcare-commons to 2.9.3 to support Spring Boot 3.3.0
• Replaced Springfox with Springdoc
• Migrated from Springfox to Springdoc using a custom SwaggerConfig to mitigate differences in the generated OpenAPI
• Replaced Swagger annotations with those from io.swagger.v3.oas.annotations
• Replaced javax annotations with jakarta equivalents
• Updated testcontainers version
• Replaced Problem with ProblemDetails in UserGroupExceptionHandler
• Moved EnableMongoAuditing closer to the SpringBootApplication annotated class
• Fixed test removing trailing slash: Spring Boot 3 resolves the trailing slash as a request to a static resource
• Excluded globalApiCustomizer bean in SwaggerConfig
