Update mosh-client.exe to latest version

[lifei]

Dear developer of FluentTerminal,

I would like to bring to your attention that the mosh-client.exe file in this project repository is outdated. It was added 4 years ago and the latest version of mosh, version 1.4, was released 2 years ago. Therefore, I kindly request you to update the mosh-client.exe file to its latest version to ensure compatibility and security.

Thank you very much for your attention to this matter.

Best regards,

L. Fee
