fix link: Section "Hardware Components"

[VladimirFokow]

on this page there is:

Section Hardware Components describes this in detail.

but the link leads back to the same page, not to the "Hardware Components" section.

Is this the intended location for this link?:
https://control.ros.org/humble/doc/ros2_control/hardware_interface/doc/hardware_components_userdoc.html#hardware-components

---

also on that page, this link leads to nowhere. I don't know where it should lead:

strings in hardware’s description

(I'm not very familiar with making PRs to this project, sorry if I don't do it)
