This is a redesign in how plugins call _remote_checksum().
- _remote_stat() has been modified to report the real error as
AnsiblError
- Action plugin **unarchive** calls _remote_stat() directly instead of
_remote_checksum()
- Action plugin **unarchive** also handles the exceptions directly
- Ensure get_exception() returns native text
Two other action plugins, **template** and **fetch**, also do a remote checksum.
In **template** we already call _remote_stat(), just like we now do for
unarchive, in **fetch** we do call _remote_checksum() and we make the
exact same mistake as the unarchive plugin. So that one could use a
redesign as well.
This fixes#19494
Before:
```
[dag@moria ansible.testing]$ ansible-playbook -v test137.yml
Using /home/dag/home-made/ansible.testing/ansible.cfg as config file
PLAY [localhost]

After:
```
