Migrate RestTemplate API calls to RestClient

Recipe IDio.moderne.java.spring.boot3.MigrateToRestClientAPI
Artifactio.moderne.recipe:rewrite-spring

Migrates Spring's RestTemplate to the modern RestClient API introduced in Spring Framework 6.1. RestClient provides a fluent, synchronous API that is the recommended approach for new development. This recipe converts constructor calls, type declarations, and common method invocations (getForObject, getForEntity, postForObject, postForEntity, patchForObject, put, delete, headForHeaders, postForLocation, optionsForAllow, exchange) to their RestClient equivalents.
