Remove bundler for deps yml

The bundler pattern had an escaping issue causing an error in deps
pipelines:

```
panic: Pattern not found in file
```

Even with the proper escaped pattern, the bundler replace did not work
as expected (it used the rubygems version instead).

Remove bundler to unblock master/deps io pipelines.
