Error when running example code for mxpx-openai-node - SyntaxError: Cannot use import statement outside a module

- I tried running the example code at https://docs.mcp.run/tutorials/mcpx-openai-node
- I get the following error after running index.js
```
/Users/rishi/Projects/mcpx-openai-chat/index.js:2 import { McpxOpenAI } from "@dylibso/mcpx-openai"; ^^^^^^

SyntaxError: Cannot use import statement outside a module at internalCompileFunction (node:internal/vm:77:18) at wrapSafe (node:internal/modules/cjs/loader:1288:20) at Module._compile (node:internal/modules/cjs/loader:1340:27) at Module._extensions..js (node:internal/modules/cjs/loader:1435:10) at Module.load (node:internal/modules/cjs/loader:1207:32) at Module._load (node:internal/modules/cjs/loader:1023:12) at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:135:12) at node:internal/main/run_main_module:28:49
```

For now, in order to fix it and run, I added type as module in package.json and renamed index.js to index.mjs (i guess either should work?)
