Subject: [PATCH] Fix exotic fold range kinds (#49151)

Follow-up of https://github.com/zed-industries/zed/pull/48611

Despite Zed not declaring such support in its capabilities,


https://github.com/zed-industries/zed/blob/a0eb63d1affb6e7b7991e477c7e05824d0250255/crates/lsp/src/lsp.rs#L1010-L1016

`json-language-server` returns `object` as a folding range kind:

/>

The spec, even 3.18, does not really seem to allow it explicitly:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#foldingRangeKind

but mentions that the real type

> The type is a string since the value set is extensible

The PR adds a capture enum variant for such cases, to get the folds in
instead of failing on deserialization.

Release Notes:

- Fixed `json-language-server` document folds not being parsed correctly
