Make Owner addressable via RFC 2822 standard

[noomorph]

Context

I find it inconvenient to have owner just as a non-actionable label – especially in environments where a person has different names in real life, email, Github and Slack/Discord.

Therefore, I'd like to suggest improving the rendering and making it follow Internet Message Format, e.g.:

John Doe <[email protected]>
John Doe <https://github.com/john.doe>

and also be able to consume plain e-mail and URL addresses:

[email protected]
https://github.com/john.doe

In the case when the owner is not a valid URL or e-mail, the rendering stays the same, e.g.:

johndoe
