readme: fix gpio config example
Commit eea8a4a5 renamed the group config key from `gpio_config` to
`group_gpio_config`. Reading a single GPIO pin is done within the
GPIO definition object.
When using the example, it'll result in a SIGABRT because it fallbacks
to the non-group parsing, expecting either a pin or num:
```
Start Phosphor buttons service...
terminate called after throwing an instance of 'nlohmann::json_abi_v3_11_3::detail::out_of_range'
what(): [json.exception.out_of_range.403] key 'num' not found
```
Tested: Start phosphor-buttons with the new example config does not
result in a SIGABRT.
Fixes: eea8a4a5 ("Fix parsing gpio config format issue")
