EndOfLife date for Debian is not consistent

[sdwheeler]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

The current matrix.json file has incorrect dates for Debian 10 and 11.

Expected behavior

The dates for a version should be the same for all Channels.

https://endoflife.date/debian has the following dates:

Release	Released	Security Support
11 (Bullseye) (Upcoming LTS)	10 months ago (14 Aug 2021)	Ends in 4 years (15 Aug 2026)
10 (Buster) (LTS)	3 years ago (06 Jul 2019)	Ends in 1 year and 11 months (01 Jun 2024)

Actual behavior

We have to EOL the image at the EARLIER of the our product end of life or the distribution end of life. This definitely does not result in consistency across channels.
