Document placeholder and Ant-style pattern support for `@Enable…Repositories`

[bilak]

Hello,
recently I was trying to find out if it's possible to use wildcard in EnableJpaRepositories#basePackages. There is no documentation about that, but seems like it works. Can we enhance documentation about it?

Thanks
