[docs] Fix example for Allman brace breaking style

[jkorous]

Summary

Commit 3fd4a968ad80 by @jkorous was wrongfully rolled back. Opening braces need to be on separate lines for Allman style.

[jkorous]

You're right, thanks for letting me know.

It was changed in 806d5741aa7f.

@owenpan was that intended?
