Subject: [PATCH] fix: allow reserved word 'mod' in exports (#21537)

This problem occurred trying to load tensorflow.js
```
> import * as tf from 'npm:@tensorflow/tfjs';
Uncaught SyntaxError: Identifier 'mod' has already been declared at file:///Users/ry/Library/Caches/deno/npm/registry.npmjs.org/@tensorflow/tfjs/4.14.0/dist/tf.node.js:167:14
    at async <anonymous>:1:33
```
