Minor improvements in the providers map in examples

[antichris]

1. Initialize provider title map instead adding values one by one.

   It's much more readable this way.

   And, technically, more resource efficient (on my system, ~-59% sec/op, ~-51% B/op, -2/3 allocs/op). Although — who cares — this only runs once and in an example.

2. Spell Battle.net the way they do.

3. Spell LinkedIn the way they do and prefer done.

Thanks so much for this PR 😃 I'm going to remove the hidden file, but will merge this PR shortly.

edit: nvm, I saw what the hidden file did, and will merge this as-is :)
