GitHub action incompatible with actions/checkout@v6

[amartani]

Description

actions/checkout@v6 changed how credentials are persisted, which results in the opencode github action workflow to fail with:

Configuring git...
846 |         // Do not change git config when running locally
847 |         if (isMock) return
848 | 
849 |         console.log("Configuring git...")
850 |         const config = "http.https://github.com/.extraheader"
851 |         const ret = await $`git config --local --get ${config}`
                     ^

Reverting to actions/checkout@v5 fixed the issue.

Yes, the current instructions in the repo do work. I had dependabot upgrade my actions, which broke my setup, and I figured I should at least report so that others can find it if it affects them.
