[Feature Request] Sort plugins by starts and by stars/download ratio

[tarekbess]

**Is your feature request related to a problem? Please describe. **
I use your website to keep up with new plugins, and to find existing valuable plugins.
The current sorting options could be further improved to make finding valuable plugins easier.

Describe the solution you'd like
I think two facets that could be very useful in the "all plugins" sort options would be "github stars" and especially "github stars/downloads".
These two facets are in my opinion correlated with how useful and valuable plugins are to users.

Describe alternatives you've considered
I considered using the "score" facet, but I don't personally agree with how weights are assigned.
Perhaps one way to improve the score feature would be to allow the user to write their own score formula i.e. ${stars/downloadsCount}

Additional context
(none)

@tarekbess thanks for the patience.

Since we support custom score functions now, these can be easily implemented and validated using custom score function.

1. By Stars

1.1 Create a custom score function

1. Go to build scorer page
2. Past the following code to calculate the score (0-100) based on star count

let stars = plugins.map(plugin => plugin.stargazers).sort((a, b) => a - b);

const outliersCount = Math.round(plugins.length * 0.005)
stars = stars.slice(outliersCount, plugins.length - outliersCount)

const min = Math.min(...stars);
const max = Math.max(...stars);

plugins.forEach(p => p.score = utils.normalize(p.stargazers, min, max))

3. Click "Validate" (This code will pass validation)
4. Give a name and description
5. Click "Create and Use"

1.2. Make sure custom score functions are enabled

In the scorer page, make sure the Enable Custom Scorers is turned on and the desired scorer is being used.

---

1.3. Sort plugins by score

In all plugins page, you can sort by "Score (High to Low)" to see the plugins sorted by the star count.

---

By stars/downloads

Create another custom score function with the following code

let starsByDownloads = plugins.map(plugin => plugin.stargazers/plugin.totalDownloads).sort((a, b) => a - b);

const outliersCount = Math.round(plugins.length * 0.005)
starsByDownloads = starsByDownloads .slice(outliersCount, plugins.length - outliersCount)

const min = Math.min(...starsByDownloads);
const max = Math.max(...starsByDownloads);

plugins.forEach(p => p.score = utils.normalize(p.starsByDownloads, min, max))

Let me know if you have any questions
