Migrating Current Electron version to Stable Electron version

[Ayush4958]

Summary

Update the current electron version to higher stable version of electron.

Changes

• In main.dev.js , i had modernize the window creation process by using promise based approach as it's prefer in newer electron version

app.whenReady().then(createWindow);

• In package.json , I had updated electron version along with its ecosystem dependency (builder , rebuild , log , updater)
  and there is change in script of start-main-dev , which is done as the older script giving error in main process .

• In yarn.lock Auto-generated the latest dependency constraints strictly correlating with the package.json upgrade.

Test

Already runs all the Test cases & It passes all in my end.

This overall seems to be working so far, but I'm confused where you got some of the version numbers that you used for the upgrade. 3 of the versions don't exist and were triggering warnings for me. Please confirm that any version number we use for a package exists.

It appears the latest version of electron-log is 5.4.3? I'm getting a warning when running setup:
Couldn't find any versions for "electron-log" that matches "^5.5.0"

Although it prompts me to select the version I want to use, we should only include currently available versions.

Yhh , These are not the valid version , I got list of version in terminal for these and selected from the list and didn't cross check if they are valid or not .
I had updated the dependencies

Same as with electron-log, the latest electron-updater appears to be 6.8.3.

There is no 24.15 of electron-builder. Do you know if this needs to work with the latest 24.* release, or can we upgrade to 26.*?

@lrasmus ,
Everything correct had been updated to correct version
