fix: release workflow version detection for Linux

[graycreate]

Summary

• Fixed version detection in release workflow to work on Ubuntu runners
• Changed from using macOS-specific plutil to using grep on project.pbxproj

Problem

The release workflow was failing because it tried to use plutil (a macOS utility) on Ubuntu runners.

Solution

Parse version and build number directly from V2er.xcodeproj/project.pbxproj using grep, which works on both macOS and Linux.

Pull Request Overview

This PR fixes the version detection in the release workflow to work on Ubuntu runners by replacing macOS-specific plutil commands with cross-platform grep parsing of the Xcode project file.

• Replaced plutil XML parsing with grep parsing of project.pbxproj
• Changed from parsing Info.plist to parsing V2er.xcodeproj/project.pbxproj
• Updated comments to reflect the Linux compatibility

[Copilot]

The grep patterns assume specific formatting of the project.pbxproj file. Consider adding error handling to check if the grep commands find matches, as Xcode project files can have varying formatting or the keys might not exist.
