Maybe let's update all nightly toolchain uses in one go?

~/Code/rust/iroh/.github main*
$ rg nightly
workflows/docs.yaml
35:        toolchain: nightly-2025-02-20

workflows/ci.yml
259:          toolchain: nightly-2025-02-20

workflows/tests.yaml
259:      - uses: dtolnay/rust-toolchain@nightly
263:          cargo +nightly check -Z minimal-versions --workspace --all-features --lib --bins
290:      - name: Install Rust nightly
292:          rustup toolchain install nightly
306:          cargo +nightly check -Z minimal-versions --workspace --all-features --lib --bins

Yeah, you are right. Missed the one in docs.yaml. For the ones in tests.yaml there is nothing to do since they don't mention explicit versions, right?

Did a quick check. Main does indeed fail with latest nightly:

@ramfox we should do a patch release with just this, to make sure docs.rs is fixed
