Summary:
Changed retrieving of Flipper version. Now it will be always retrieved from package.json. Before this change we used "remote.app.getVersion()" API which instead returned electron version for dev builds, e.g. "11.2.3". This is not convenient, because we now use Flipper version to check plugin compatibility and unrelated Electron version here makes things more complicated. After this change, if version is not properly bumped then "0.0.0" will be used: 1) when running using "yarn start", 2) when local building with "yarn build --mac" without setting new version, 3) when running tests "yarn test".
In addition to that I added a new command-line argument and env var which allow overriding version number for Flipper. This is useful for testing plugin updates, because compatibility between plugins and Flipper is checked by comparing Flipper version with the min version set in the plugin metadata.
