Decap CMS - change commit's author to someone other than DoomHammer

[MartaSien]

Description of the issue

Currently, when creating a new PR via Decap CMS, the author is always @DoomHammer .
Sample PR with the issue: Create [ENG] Projects “żeton”

How it should be?

When opening a PR via Decap CMS, the author should be, if possible, a creator of the PR. If it's not possible, perhaps the author could be something akin to a faceless account.

Implementation plan

One option is to change the backend to GitHub. This way, a user will have to authorize via their GitHub account to use Decap CMS dashboard.
I tested creating the PR and it worked: MartaSien#18
It can even create a fork automatically.

The process is described in docs here.
