How can I find out the latest stable Jenkins version via API call?

I'm trying to write a script that creates a Docker image from a Jenkins image, that is, the first line of my Dockerfile is...

FROM jenkins/jenkins:2.249.3

However I wanna be smart and write a script that gets the latest Jenkins stable version and sed that into my Dockerfile, like this

Dockerfile:
FROM jenkins/jenkins:JENKINS_LATEST_STABLE_VER

$ export JENKINS_LATEST_STABLE_VER=`some_api_call`
$ sed -i "s/JENKINS_LATEST_STABLE_VER/$JENKINS_LATEST_STABLE_VER/g" Dockerfile
$ docker build ...

What is "some_api_call"?

latest stable:

curl -L --max-redirs 2 https://updates.jenkins.io/stable/latestCore.txt

latest current:

curl -L --max-redirs 2 https://updates.jenkins.io/current/latestCore.txt

Building off of Ian's comment

https://updates.jenkins.io/current/latestCore.txt

https://updates.jenkins.io/stable/latestCore.txt

is one way to get the latest version, but read through the document in that comment.

I also found this answer which agrees

Jenkins - get latest artifact with curl
