Allow Customization of Drupal Logo on Gutenberg Editor Edit Screen

There's this workaround for now (not tested). Taken from #Gutenberg channel:

I believe you can override the react component responsible for the button.
So this is the "Back Button" component:
https://git.drupalcode.org/project/gutenberg/-/blob/3.0.x/js/components/...

You could create your own component and override the global var:
window.DrupalGutenberg.Components.BackButton = [your-component];

And then override the library settings:
https://git.drupalcode.org/project/gutenberg/-/blob/3.0.x/gutenberg.libr...

@marcofernandes I have tried the above workaround and it works fine with me. It will be good to have it in the Gutenberg core.
