Add docker support

[PuppetMaster2k]

I would like to have the possibility to run vscode-as-mcp-server as a docker container.

The dockerfile could look something like this:

FROM node:22-alpine

WORKDIR /app

# Expose default port if needed (optional, depends on MCP client interaction)
EXPOSE 60100

# Default command to run the server
CMD ["npx", "vscode-as-mcp-server"]

I have tried somehting similiar, directly within Claude Desktop, but running vscode-as-mcp-server in docker, cannot connect to vscode.

{
  "mcpServers": {
    "vscode": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm", "-p", "60100:60100", "node:22-alpine", "npx", ["vscode-as-mcp-server"
      ]
    }
  }
}
