k3s: init 1.27.1+k3s1

On unstable, we're now tracking

| version | EOL |
|---------|-----|
| 1.24    | 07/2023 |
| 1.25    | 10/2023 |
| 1.26    | 02/2024 |
| 1.27    | 06/2024 |

This commit adds 1.27 using the 1_26 builder introduced in the last
commit.

Notably, this commit also updates the 'update.sh' script to work for the
new setup I have here.
