Remove tests and documentation for Quarkus Amazon Services integration

[jamesnetherton]

Some simplification of AWS support on CQ.

• Removes Quarkus Amazon Services tests
• Removes documentation references to Quarkus Amazon Services
• Adds a note to the migration guide about the preferred CQ AWS usage
• Continue to sync, align and test with the AWS SDK version that Quarkus Amazon Services uses. Since this version will be forced on us in the platform.

I left quarkus-amazon-services-bom imported in camel-quarkus-bom-test as it'll enable Dependabot to continue doing auto upgrade PRs to bump the AWS SDK version property.
