running command `cargo dist generate` in a branch different than `main` not updating github workflow

[Masber]

Dear cargo dist team,

I am trying to update the github runner in my giuthub pipeline generated by cargo dist. I changed the github runner to ubuntu-22.04 here https://github.com/eth-cscs/manta/blob/1.5/dist-workspace.toml under branch 1.5

Then I ran cargo dist generate and cargo dist init

Then I check the github pipeline under .github/workflows/release.yml but the github runner still points to ubuntu-20.04

Any idea why? I suspect it is because I am not in main branch
