extension_host: Remove duplicate linker registration (#25361)

This PR fixes a panic that would occur when loading an extension using
v0.2.0 of the extension API after #25357 landed:

```
Thread "<unnamed>" panicked with "called `Result::unwrap()` on an `Err` value: map entry `zed:extension/github` defined twice" at crates/extension_host/src/wasm_host/wit.rs:38:31
