Cannot expand the electron 2 vscode PR

We ran into exceptions when dealing with file changes returned from GitHub. When a file or change is large, GitHub will not return the diff hunk for that change but we didn't protect that.

[rebornix]

There are several cases that GitHub pull request api doesn't return a file change with proper patches/diffs

1. file or diff is too large
2. file is binary

For the first case, we can probably fetch the blob content from github, but we don't know for sure if we can open the binary content successfully in vscode. So for now we will open the file directly in browser.

Reopen it and see if we can have enhancement from the api side.

I also see this for a small PR: microsoft/vscode#73775

@mjbvz 👍 this looks like #1059, sent out a fix for it

Closing since we should now handle file changes that don't have blob content by showing a notification to open them on GitHub
