networks: Minor changes to router/internet configuration forms

- Cosmetic styling fixes. Having doc string as suggested by Python doc string
guidelines.

- 'connected to the Internet' seems much more popular phrase than 'connected on
the Internet' judging by web search results.

- Stylize as 'Internet' for consistency although 'internet' is correct too.

- Add space at the end of main radio button option text as translators seems to
understand it incorrectly. See current Spanish translation.

- Recommend 'DMZ' for router configuration.

- Remove incorrect title casing port forwarding text.

- Internationalize some strings.

- Update the default value for router configuration to 'not_configured'.

- Update the default value for Internet connection type to None so that nothing
is selected by default. We could consider introducing a fourth option
'not_configured'.

- Update the ID of first boot wizard step for Internet connectivity.
