libpod/containers/json: alias last -> limit

Support both `last` and `limit` for in the containers listing endpoint.
We intended to use `limit` which is also mentioned in the docs, but the
implementation ended up using `last` as the http parameter; likely being
caused by the CLI using `--last`.  To avoid any regression, we decided
for supporting both and aliasing `last`.

Fixes: #6413
