BUGFIX: Correct node naming scheme in nodetype definition example

[Sebobo]

The example uses an outdated camelcase variant for node names.

Relates: Sebobo/Shel.Neos.Schema#26

Thank you! This is absolutely right.

[mhsdesign]

Thanks makes sense, though there is at least one someChild reference still in the text leftover.

[dlubitz]

@mhsdesign is referring to:

This adds a new ContentCollection called someChild to the default page.
It will be positioned before the main ContentCollection that the default page has.

In Line 75
