[FEAT] - Add `--version` flag

[bakayu]

Add --version Flag to Display Binary Version

Current Behavior:

There is currently no straightforward way for users to check the installed version of the gitx binary.

Desired Behavior:

Add a --version flag that, when used, prints the current version of the application and then exits. This is a standard feature in command-line tools and improves usability. The version should be taken from the latest tag pushed in the master branch.
Example usage:

gitx --version
gitx version: 1.2.2

PR Acceptance Criteria:

• Running gitx --version in the terminal should print the application's version number.
• The version number should be dynamically injected into the binary at build time to ensure accuracy.
• Attach a screenshot of the terminal output after running the gitx --version command.
