Follow-up of https://github.com/zed-industries/zed/pull/26574/files After that PR, settings.json stopped giving completions when `"` was typed as a key: https://github.com/user-attachments/assets/5ff03863-024c-4c28-a7cd-8ef48a1695d8 This goes down to https://github.com/zed-industries/zed/blob/fb12863999e601c4ffc9afbded036e4f1f064369/crates/language/src/language.rs#L1736-L1748 which was empty before the PR, hence leading to lower `true` branch. Now, when typing `"`, there's no scope according to https://github.com/zed-industries/zed/blob/fb12863999e601c4ffc9afbded036e4f1f064369/crates/project/src/lsp_store.rs#L4529-L4532 return result. Removing `json-language-server` from `scope_opt_in_language_servers` seems to preserve the `:` fix and restore the completions behavior. Release Notes: - N/A
