OpenCollective widget doesn't allow for dofollow links [bounty: 123 XTR]

[DreadKnight]

Requesting a small patch for an issue that's in another project that's affecting this project and many others by extension.
It hasn't been touched in quite a while so I'm trying to grease the wheels by making people more aware of the issue and also offering a bounty for fixing it. The bug can be found here -> opencollective/opencollective#5968

Problem:
The Open Collective widget showcasing backers/sponsors has all the links with the "nofollow" attribute. Some backers/sponsors want "dofollow" type of links in order to improve SEO, having search engine crawlers improve their ranking.

Expectation:
Should have setting for Open Collective tiers in order to mark them for default "dofollow" type of links, basically not including the "nofollow" attribute tag.

Solution:
Open Collective tiers should have a setting with a off/on type of button, description saying "nofollow" links and being set to "on" by default.

Reasoning:
This way a lot of backers/sponsors that care for SEO can be pleased and collectives can make the proper changes, perhaps allowing "dofollow" type of links for rather premium tiers, as it can theoretically affect website SEO.
