management.ssl.enabled property is documented with a typo

[plaird]

This doc page:

http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-monitoring.html

has the example:

management.port=8080
management.ssl.enable=true
management.ssl.key-store=classpath:management.jks
management.ssl.key-password=secret

in my testing, the 'enable' property should be documented as 'enabled', as in:

management.port=8080
management.ssl.enabled=false

to match the field in this bean:
