fix: Quote $SDKMAN_DIR in version subcommand

[hyperupcall]

With this change, the version subcommand now works if $SDKMAN_DIR includes newlines, etc.

Hi @hyperupcall, the version subcommand has been obsolete for a long time and is replaced by the Rust equivalent over here:
https://github.com/sdkman/sdkman-cli-native/blob/master/src/bin/version/main.rs

If you are having issues with the version command, please have a conversation with us on Slack so we can raise an issue to fix it properly.

[hyperupcall]

Thank you for your quick response! I see, the equivalent Rust code is always ran instead (assuming they use the installer and are on one of sdkman-cli-native's 5 supported architectures). In that case, I will close this issue since it doesn't actually change anythig. Maybe there can be a comment at the top or the file can be deleted to prevent confusions like this in the future

No probs, and do let me know if you have any issues. We'll probably begin removing these legacy files soon, but I'll update the project README with some more details.
