ci: github token does not have the right permissions

[obatirou]

https://github.com/kkrt-labs/keth/actions/runs/12315767850/job/34374653110

It seems it needs to use a special token with greater permissions

Currently the action has

permissions:
      actions: write

It should be sufficient

Try to use the kakarot bot app token for this
