more specific bean name for objectMapperProvider

The bean name is very generic. Application context failed to start up for me because in the graphql kickstart library there's a bean with the same name.

See https://github.com/graphql-java-kickstart/graphql-spring-boot/blob/13cd484f913fe7885ff5d5bc5883b1e9544d4ca6/graphql-spring-boot-autoconfigure/src/main/java/graphql/kickstart/spring/web/boot/GraphQLWebAutoConfiguration.java#L269

Therefore I propose a more specific bean name.
