Wildcard: `<NavMenu />` Manual migration

Created by: umpox

Manual migration required to update our code to use the <NavMenu /> Wildcard component.

See Wildcard V2 - Planned work for more context

Note: Before doing this, we should check if there is scope for a codemod to automate this migration. If so, the codemod should be implemented and ran before starting work on this issue.

Acceptance criteria

• All incorrect usage of the previous pattern has been updated to use the Wildcard component
