This PR changes v0.0.7 of the extension API to v0.1.0.
We had a false-start in releasing v0.0.7, which has since been yanked,
so we need a new version number. We'll publish v0.1.0 to crates.io once
the Preview build is out tomorrow.
We're incrementing the minor version so that we have some leeway in
putting out patch releases of the crate within a given extension API
release.

This PR updates the README of the `zed_extension_api` crate to show the
compatibility between different versions of `zed_extension_api` and Zed.
