This PR is intended to resolve #30432.

I've formatted the Spring Security examples consistently such that - the last word of the respective method name is chosen as the variable name in the lambda, - withDefaults() is used where no actual Customizer is used, - chaining is not used as that is sometimes hard to style nicely if lines are continued.

If a different style is preferred, I'll be happy to change it.
