[FEATURE REQ] Spring boot 4.x / spring framework 7.x compat

[davidkarlsen]

Is your feature request related to a problem? Please describe.

Spring-boot 4.x support.
While not yet released you should probably start to adopt as historically releases has been a bit slow.
Example of failing calls:

java.lang.IllegalArgumentException: Unable to instantiate factory class [com.azure.spring.cloud.autoconfigure.implementation.keyvault.environment.KeyVaultEnvironmentPostProcessor] for factory type [org.springframework.boot.env.EnvironmentPostProcessor]

Describe the solution you'd like
Compatability with spring-boot 4.x. Migration guide on notable changes in your SDK.
Result: users can pick up the new release and make it work with SB 4.x with clear actions on how to transition from old to new version.

Describe alternatives you've considered
N/A

Additional context
Maybe cut some RCs to have user-base test and report back.
