Remove transitive dependency on `mio`

[SandroHc]

Removes the transitive dependency on mio. This allows projects targeting wasm32-unknown-unknown to compile. Fixes #1282.

The mio dependency is being brought in via: juniper_axum→axum→axum/tokio→tokio/net→mio. By disabling the default features of axum, we disable its tokio feature.

axum's comment on mio:

mio, tokio's IO layer, does not support the wasm32-unknown-unknown target which is why this crate requires default-features = false for axum.

Reproduction Steps

1. Install the "wasm32-unknown-unknown" target rustup target add wasm32-unknown-unknown
2. Create a dummy WASM library cargo install cargo-generate && cargo generate --git https://github.com/rustwasm/wasm-pack-template
3. Add "axum" cargo add axum@0.7.5 --no-default-features
4. Add "juniper" cargo add juniper@0.16.1
5. Confirm that project builds cargo build --target wasm32-unknown-unknown cargo tree --target wasm32-unknown-unknown --invert mio (no matches is what we want)
6. Add "juniper_axum" cargo add juniper_axum@0.1.0
7. Project no longer builds cargo build --target wasm32-unknown-unknown cargo tree --target wasm32-unknown-unknown --invert mio
