feat: add -V/--version flag

[sitiom]

Add new flag to show basic version information:

    -V, --version Print version information

Example:

> sshpass -V
sshpass-win32 1.0.7

Note: Don't forget to update the version in CMakeLists.txt for every new release

The version number should be automatically set via git tag:
When running an action each time, obtain the latest tag and pass it to CMakeLists.txt via environment variables or CMake parameters, or directly retrieve the tag within CMakeLists.txt

Thanks. I've now done the following:

1. Read the version from SSHPASS_GIT_TAG parameter
2. If parameter does not exist, fetch the latest tag from git
3. Else, fallback to 0.0.0

I have also updated the github actions in the workflow and added Dependabot for automated update checks.
