feat: add star count for each plugin

[NikitaRevenco]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)
• If applicable, I’ve added docs and tests

Description of changes

Stars help me quickly filter the plugins to decide which ones I want to try out, and this PR adds that for every plugin!

Thankfully we have AI otherwise this would take me like 2 hours 😄

Heya! I think there’s sometimes something to say for data such as this. Quantitative. And you can use GH to do that: you can search for the topic remark-plugin, or a more general search for remark.

But there’s also something for without. Qualitative. And that’s this list. A list we maintain. Where people can add things. And we look at whether it’s a good and recommended approach.

There are very good plugins with very few stars.
There are pretty bad plugins with many stars.

I’d prefer this list without the stars. /cc @remcohaszing @ChristianMurphy

I kind of like the idea, but I agree with @wooorm’s points.

Also the list looks visually less appealing to me with these badges.

Ok, I can see where you guys are coming from!

I'm neutral on adding stars or other stats like download count.
If we did add these, the plugins section should be reworked as a table.
