without this change when adding the vault token `spring.cloud.config.server.vault.token` we have 2 config token providers on the classpath, the `VaultConfiguration#configTokenProvider` and the `EnvironmentRepositoryConfiguration$DefaultConfigTokenProvider` both with the same bean name. Starting from Boot 2.2 (AFAIR) that's unacceptable by default.
with this change we're changing the bean name so that we don't override the other bean name.
