Working on fixing unit test

[fabiankaegy]

@Mayank-Tripathi32 looks like there is already a PR for this one #67904

But that one also has the same issue with the unit tests. So feel free to collaborate in case you already have a solution for the tests :)

I tried to figure it out, but most issues occur on mobile, and I'm unsure how to fix them. If you have any resources, I'd be happy to try again.

Thanks for the PR!

I think the unit test failure is based on the fact that ToolsPanel and ToolsPanelItem are not available in the React Native version. There are two solutions:

1. Split the Edit component into a web version and a React native version. That is, create a edit.native.js file for the React Native version. Leave the Edit component unchanged in the React native version.
2. Render the component conditionally using Platform.isWeb or Platform.isNative.

I think the latter approach is better for the Gallery block, since the Platform is already used for block controls etc.
