[Reference] Sort debug options alphabetically

Sorting the options of Configuration Reference was always important ... but after symfony#20712 this is even more important.

There are only two documents to sort: `debug` and `framework`. This PR updates the first one, which is trivial. But fixing `framework` will take a lot of effort (and would be a merge conflict nightmare). That's why I propose to do this only in 7.2 branch and up.
