Use sensible email adress for git in altinn studio

Description

@ivarne was going through some old bugs and found this in one of the comments 😂 Not sure why we never did anything about this, but I see no reason to not just incorporate this change now!

The likely reason I did not click "open PR" is that I didn't have the time to run studio locally and verify that it actually worked.

Something weird about the checks 🤔 Might be because I used the wrong base branch when I created the PR. I copied the code into a new branch and created a new PR, all checks run green: #12522
Also tested that branch on my machine, it works as expected there 🥳

Tested in dev - works like a charm.
One thing to note is that the email addresses differ when making changes in Altinn Studio compared to making them directly in Gitea.
When committing changes in Gitea directly: @noreply.altinn.no
In Studio: @noreply.altinn.studio
I'm not sure if this is intentional, or if we should use the same email address.
What are your thoughts, @nkylstad, @framitdavid ?

Gitea config:

I would guess (hope) the reason for the discrepancy is that gitea(studio) changed their default committer author email after I suggested this for studio. Otherwise I made a mistake. The point was to make them equal. (Although it might be reasonable to make it more obvious where the commit was generated)
