Link on the bottom of the website does not lead to this github repository

On e.g. https://docs.arduino.cc/language-reference/en/variables/utilities/PROGMEM/ there is a link to the github at the bottom:

> The content on [docs.arduino.cc](https://docs.arduino.cc/) is facilitated through a public [GitHub repository](https://github.com/arduino/docs-content-reference). If you see anything wrong, you can edit this page [here](https://github.com/arduino/docs-content-reference/edit/main/content/en/02.variables/01.constants/floatingPointConstants/variable.md).

But it does not point to this repo, but not (anymore?) existing https://github.com/arduino/docs-content-reference

This link does not seem to exist in this repo, but figured it would be an appropriate enough place to report it anyway.

Open the reported docs.arduino.cc page and search this repository for the obsolete docs-content-reference URL. Update the footer link to the correct repository and verify that both the repository and page-edit links resolve from the rendered page.
