Implementation of man pages for Volta

Solution for #1709

This PR adds support for generating man pages in Volta, using the clap_mangen crate.

Key Changes

• Added clap_mangen dependency to the project.
• Created a new man_pages module in src/command/.
• Implemented a new ManPages struct with Volta's Command trait.
• Added a new ActivityKind for logging man page-related events.
• Utilized the Man struct from clap_mangen to generate man pages from Volta's command.
• Implemented logic to emit the generated roff content to the appropriate location based on the operating system.
• Updated the installation script to include man page generation and placement during installation.

Special Considerations

• Implemented support for Windows, despite the lack of a standard location for man pages on this operating system.(WIP)
