fix(templates): ignore wrangler when bundling to fix template styles (#14067)

### What?
Adds the missing `/* webpackIgnore: true */` annotation when importing
wrangler, as in the original OpenNext patch.

### Why?
It looks like Webpack messes up the template styles when bundling the
Cloudflare template, which causes some issues such as black text on
black background or larger than usual font size.

### How?
By telling Webpack to ignore wrangler when bundling.

This solution was found by @nwong212 in the original issue, I'm just
submitting the fix after checking my self that it indeed fixes the
bundling.

Fixes #13989
