Unhandled exception running "legendary list" with wi-fi down

[RocketHog55]

Platform

Operating system and version: Windows 10
Legendary version (legendary -V): 0.20.27

Expected Behavior

ConnectionError Exception should be handled similar to HTTPError, with the "HTTP request for login failed" log message.

Current Behavior

With the wifi off, legendary auth fails with an unhandled ConnectionError exception.
output:

[11008] Failed to execute script 'cli' due to unhandled exception!`

Steps to Reproduce

1. Turn off wifi
2. run legendary list

Additional information

Fix is simple, in core, import ConnectionError along with HTTPError from requests.exceptions, and in login(), handle ConnectionError the same as HTTPError:

        except (HTTPError, ConnectionError) as e:
            self.log.error(f'HTTP request for login failed: {e!r}, please try again later.')
            return False
