Make npm package compatible with Windows

[allisterb]

I'm able to compile and use this language server on Windows:

$ npm run build:cli

> [email protected] build:cli
> tsup src/server.ts -d dist/cli && sh scripts/add_shebang.sh dist/cli/server.js

CLI Building entry: src/server.ts
CLI Using tsconfig: tsconfig.json
CLI tsup v7.1.0
CLI Using tsup config: c:\Projects\vscode-solidity\tsup.config.ts
CLI Target: es6
CLI Cleaning output folder
CJS Build start
CJS dist\cli\server.js 122.84 KB
CJS ⚡️ Build success in 1478ms
'sh' is not recognized as an internal or external command,
operable program or batch file.

Just the last step of running the sh script won't work in a Windows environment.

However I cannot install the npm package:

$ npm install @llllvvuu/vscode-solidity-langserver

Same thing if I pack and try to install locally from the vscode-solidity repo folder.

I'm not a node developer so I'm not sure which dependency is causing this. This is from the log file:

1357 verbose stack Error: Unsupported platform

However I've been using the language server in my own Windows-based project and haven't encountered any issues or Windows incompatibility.
