docs: replace invalid 'hermes config get <key>' with 'hermes config show'

'hermes config get <key>' is referenced in three guides but is not a
valid subcommand. The valid subcommands under 'hermes config' are
{show,edit,set,path,env-path,check,migrate}. 'hermes config show' is
already used elsewhere in the docs (including 'hermes config show |
grep <pattern>' in the FAQ), so it's the idiomatic replacement.

- work-with-skills.md: 'View all skill config' now uses
  'hermes config show | grep ^skills\.config'
- migrate-from-openclaw.md: session-policy check now reads the value
  from 'hermes config show'
- configuring-models.md: 'inspect what the CLI will actually use'
  now uses 'hermes config show | grep ^model\.'

 `hermes model` walks you through picking a provider, authenticating (OAuth flows open a browser; API-key providers prompt for the key), and then choosing a specific model from that provider's curated catalog. The choice is written to `model.provider` and `model.model` in `~/.hermes/config.yaml`.
