Fix trailing space in ec2_vol example, fix 'the the' typos (#28440)

* Fix 'the the' typos, fix 'pahting' filename typo

* Change 'the the' typos to a single 'the'.
* Change `playbook_pahting.rst` to `playbook_pathing.rst`.

* Delete trailing space in ec2_vol example

Delete the trailing space in `instance: "{{ item.id }} "`, which makes the
example fail when run because it looks for instance "i-xxxx ".
