Che: References to commits are broken in Help -> About dialog

[RomanNikitenko]

Describe the bug

Help -> About dialog contains references for commits to theia and che-theia projects
The references are broken at the moment for master branch assembly (eclipse/che-theia:next)

Che version

• [ ] latest
• [ ] nightly
• [x] other: eclipse/che-theia:next

Steps to reproduce

1. Add to a devfile the section:

- 
    alias: theia-editor
    reference: >-
      https://raw.githubusercontent.com/eclipse/che-plugin-registry/master/v3/plugins/eclipse/che-theia/next/meta.yaml
    type: cheEditor

1. Start a workspace from the devfile
2. Go to Help -> About dialog and try references to theia and che-theia projects
3. You can see https://github.com/theia-ide/theia/commit/N/A in an address line of a browser and error: 404 Page not found

Expected behavior

The references link to relevant commits

Additional context

[ibuziuk]

@RomanNikitenko are you planning to work on this issue for Che 7 GA ?

[RomanNikitenko]

The issue is relevant for eclipse/che-theia:next, so for master branch assembly, I don't think we need it for GA.

moving to 7.1.0 milestone
