Remove native feature entry from docs.rs metadata

[silwol]

The native feature is no longer present, but was still in the list of
features to be enabled when building the documentation for docs.rs,
causing the build there to fail. Removal should re-enable the build of
the documentation for docs.rs.

Closes: #3066

Good,

It'd also be a good idea to add a new commit adding these new features in the docs:

wasmer-artifact-load 
wasmer-artifact-create 
static-artifact-load 
static-artifact-create

It'd also be a good idea to add a new commit adding these new features in the docs:

These reference the respective feature with the same name in wasmer-compiler, I assume it makes sense to enable them inside that crate as well, otherwise we might attempt reference types inside wasmer-compiler that are not rendered there.
