feat: Define custom raftify-cli --version command

[CHOUMnote]

Resolves: #155
This PR improves the version display behavior in raftify-cli:

-V option: Now shows only the raftify-cli version, maintaining its original purpose.
--version option: Displays both the raftify-cli version and the raftify version, providing a more comprehensive version report for the CLI and the underlying library.

Now the --version command now print the version of the built raftify-cli and raftify crate, along with a list of features enabled in the raftify crate.

❯ raftify-cli --version
raftify_cli 0.1.82
(Built with raftify 0.1.81, Enabled features: heed_storage, inmemory_storage, rocksdb_storage)

@CHOUMnote Thanks!
