Fix bad_weak_ptr in createBond() by using shared_ptr (backport #5341)

[mergify]

This PR fixes a bad_weak_ptr error caused by passing a std::unique_ptr to (main)nav2_ros_common::createBond()( and nav2_util::createBond() in humble), which expects a std::shared_ptr. The incorrect ownership type led to invalid weak pointer dereferencing. This change ensures correct usage of shared_ptr to avoid runtime errors during bond creation.

• Replaces unique_ptr with shared_ptr where required
• Resolves bad_weak_ptr error in lifecycle bond handling
• Fixes [Humble][macOS M2] bad_weak_ptr in nav2_util::LifecycleNode::createBond() due to unique_ptr with shared_from_this() #5335
