Failed to install using curl get.keptn.sh due to GitHub API Ratelimit

I just tried to install using the suggested method in quickstart (curl get.keptn.sh | bash). It failed due to an API Rate Limit hit on GitHub:

$ curl -sL https://get.keptn.sh | bash

An error occured while trying to download keptn from GitHub. Please manually download a release from https://github.com/keptn/keptn/releases.

Within our get.keptn.sh script, we are trying to query the latest as well as all releases of Keptn, e.g.:

curl --silent "https://api.github.com/repos/keptn/keptn/releases"

When executing this command, we get a response with the rate limit showing up:

{"message":"API rate limit exceeded for AB.CD.EF.GH. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)","documentation_url":"https://docs.github.com/rest/overview/resources-in-the-rest-api#rate-limiting"}

edit: This also affects our nightly tests using MacOS: https://github.com/keptn/get.keptn.sh/actions/runs/1776225287
