Contributors page only shows contributors to 30 repositories in Source Academy instead of all of them

[mug1wara26]

The contributors page https://sourceacademy.nus.edu.sg/contributors does not show every repository under the Source Academy GitHub organisation. This is because when getting the list of repositories in

frontend/src/pages/contributors/subcomponents/ContributorsGithubApi.ts

Line 7 in 72a7e51

const apiRepoDetails: string = 'https://api.github.com/orgs/source-academy/repos';

The REST API defaults to 30 repositories due to pagination. To fix this, the API endpoint can take in a per_page argument like so:
https://api.github.com/orgs/source-academy/repos?per_page=100
This will work until the organisation has more than 100 repositories.

The Contributors list also has the same issue, where only the top 30 contributors are shown, with dependabot[bot] and dependabot-preview[bot] filtered out, though I'm not sure if we want all contributors to be shown as some repositories have 100+ contributors

The renovate bot should also be excluded from the contributors list for consistency

I also just noticed that if you reload the contributors page a few times, you will get rate limited by the GitHub API, maybe this can be run once as a build step instead?

EDIT: The api responses should be cached, so it should be fine, but if the user used the github api before loading the page, they might hit the rate limit

Duplicate of #2251, but since this has more context, I'll close the other one.
