Add ability to upload dist release if repo owner is customized

[ZIMkaRU]

This PR adds ability to upload a dist release if the repo owner is customized

---

The idea is the following:

• have the ability to set custom repo owner for auto-update
• it's useful for beta and main releases made against the forked repo
• as the electron-builder does not support separate customization of repo owner for publishing and auto-update
• if the custom repo owner is set
• and its set value is different from the current actual repo owner
• turn off the publishing feature of the electron-builder functionality
• and then use actions/upload-artifact@v4 after being built to upload binaries to the Artifacts section of the Build release workflow like shown here https://github.com/ZIMkaRU/bfx-report-electron/actions/runs/8276698230
