Describe the bug
Victory blows up when you include a string or number as a child of VictoryChart.
The usual case where we might have a string is when we render a child conditionally and the condition is falsey with a 0 or empty string.

The error message in the header of this issue is from Victory Native, but, as pointed out in this comment it happens in Victory DOM as well:

Unhandled Runtime Error TypeError: Cannot read properties of undefined (reading 'name')

The line of code responsible for this:

It assumes the child always has props but that's not the case for strings or numbers.

Victory version
victory-native@36.5.3

To Reproduce
Try rendering this:

<VictoryChart>
    a
</VictoryChart>

Expected behavior
In the process of collecting names, children as such should be ignored.
