🐛 Consent popup points to Google's privacy and cookie policies

## 🐛 Bug Report

### Current behavior

The consent popup that's displayed on first visit on amp.dev points to Google's privacy and cookie policies.

Please also provide:
- Page link: all pages on first visit

### Expected behavior/code

The consent popup should point to the relevant OpenJSF policies (as is already done in the footer).

I believe [this](https://github.com/ampproject/amp.dev/blob/a6817519c19987b8a700110e9909f3c3bafce769/frontend/templates/views/partials/consent.j2#L33) is the line that needs to be fixed. Happy to submit a PR if that's the only change required (I don't know how your build mechanism works).

### Reproduction procedure

1. Clear stored data for amp.dev
2. Refresh the page
3. Check the links and text of the consent popup that shows up.
