extension_host: Expand supported extension API range to include v0.7.0 (#38529)

This PR updates the version range for v0.6.0 of the extension API to
include v0.7.0.

Since we bumped the `zed_extension_api` crate's version to v0.7.0, we
need to expand this range in order for Zed clients to be able to install
extensions built against v0.7.0 of `zed_extension_api`.

Currently no extensions that target `[email protected]` can be
installed.

Release Notes:

- N/A
