fix: add suggestion how to fix importing CJS module (#21764)

```
$ cat exports_error.js
Object.defineProperty(exports, "__esModule", { value: true });

$ deno exports_error.js
error: Uncaught (in promise) ReferenceError: exports is not defined
Object.defineProperty(exports, "__esModule", { value: true });
                      ^
    at file:///exports_error.js:1:23

    info: Deno doesn't support CommonJS modules without `.cjs` extension.
    hint: Rewrite this module to ESM or change the file extension to `.cjs`.
```
