fix(alpine): fix package.json's bin to alpine-language-server

[yaegassy]

For example, if @volar/vue-language-server is already installed when performing a global installation, the bin name will be duplicated and the installation will not be possible.

$ npm i -g @volar/alpine-language-server
npm ERR! code EEXIST
npm ERR! path /Users/yaegassy/.nvm/versions/node/v16.15.1/bin/vue-language-server
npm ERR! EEXIST: file already exists
npm ERR! File exists: /Users/yaegassy/.nvm/versions/node/v16.15.1/bin/vue-language-server
npm ERR! Remove the existing file and try again, or run npm
npm ERR! with --force to overwrite files recklessly.
