LSP Installer

This script automates the installation of several Language Server Protocol (LSP) tools, primarily by downloading them from GitHub and installing them on your system. The latest version of the script (and also complete) can be found here.

The script uses standard library functions to simplify the process of downloading, unpacking, and installing various LSP tools. It checks for necessary permissions, downloads the latest releases of selected LSPs, moves them to system directories, makes them executable, and installs additional LSPs using npm, pip, and gem as needed.
For each tool, if the download or installation fails, an error message is displayed, and the script exits to prevent partial installations.
