Fix resolc-bin push auth (#543)

Pushes to `resolc-bin` 403ed after bumping `actions/checkout` to `v6`
(detected by [failure of the nightly
release](https://github.com/paritytech/revive/actions/runs/27049132601/job/79841157330)).
This PR now passes the app token to the resolc-bin checkout via
[`token:`](https://github.com/actions/checkout/blob/df4cb1c069e1874edd31b4311f1884172cec0e10/README.md?plain=1#L66-L76)
and drops the remote-URL/sed workaround.
