Bug - ToolbarContent - vertical alignment does not work

[KevinFCormier]

Describe the problem
When using the alignItems="center" prop on a ToolbarContent component, a text toolbar item that is not as tall as other items is vertically at the top rather than being centred.

How do you reproduce the problem?
PF4: vertical centering was the default

PF6: vertical centering is no longer the default, but using alignItems="center" on the ToolbarContent component achieves the desired result

PF5: alignment does not work with the same changes as for PF6

Expected behavior
There should be a way to vertically center when using PF5.
