Nav - add wrapper to Nav link item text by default

[tlabaj]

Describe the enhancement or change A clear and concise description of the request. What is the expected outcome?

Update NavItem to add the Nav link text wrapper (.pf-v5-c-nav__link-text) by default instead of as an opt-in. Remove the hasNavLinkWrapper opt-in prop.

In addition to the above, as part of the work from https://github.com/patternfly/patternfly/pull/6704#pullrequestreview-2086095202 we will need to add a prop for an icon that must be rendered before the link text.

This should be ready to work on now, work was done in https://github.com/patternfly/patternfly/pull/6704. And as @thatblindgeye mentioned in https://github.com/patternfly/patternfly-react/issues/9755#issuecomment-2138000772, there is a separate enhancement (that depends on the nav text wrapper) to add icon support to nav items. Not sure if we want a separate issue for that, or just include it as part of this update @tlabaj?
