Packaging: Debian: Update repo URL, contact and Copyright

[hoffie]

Short description of changes

Our debian packaging metadata still referred to https://github.com/corrados/...
It also still listed Volker as point of contact.
This PR changes those references to jamulussoftware and team@jamulus.io.
It also updates tools/update-copyright-notices to check the Debian Copyright: line as well.

cc @mirabilos I think you once said that you use independent control files for the official packaging. You might want to check if updates are needed there as well (or you might have spotted it earlier than us ;)).

Context: Fixes an issue?

Probably did ☻ The official packaging is much more invested than that in the repository, and double-checked by ftpmasters. You cannot mechanically do these things anyway. Often, I even include copyright notices that don’t show up in upstream but are found during review… (or made necessary due to the format they like to use). bye, //mirabilos -- This space for rent. https://paypal.me/mirabilos to support my work.

Since (unless I'm wrong) Volker did it almost alone at the beginning, I'd suggest:

• Copyright: 2004-20XX Volker Fischer
• Copyright: 20XX-2022 The Jamulus Development Team

(with replacements of the XX by relevant year)

2019 was the first time anyone but Volker appears in the commit history -- but I'm not sure how accurate that is as he wasn't that au fait with git to start with and did some manual merge / fix / commit cycles that lost history. (Also, the history was ported from CVS to SVN, and I've no idea if there was any history loss in terms of committed, at that point, nor when the repo came to Github from Sourceforge.)

Certainly 2019 is about the time I seem to have been working on the Reaper recorder code. I've some vague recollection of contributing something before that but I can't find it (the original SourceForge history is gone, of course, but the import I did independently also shows no sign of anyone but Volker). The AUTHORS and ChangeLog files also have no one else's name.
