Add support for TM Segment Batch Operations

The Crowdin API adds a **TM Segment Batch Operations** method:

- `PATCH /tms/{tmId}/segments` (`api.tms.segments.patchBatch`)

The request body is an array of JSON Patch operations:

- `add` with path `/-` and a segment create form as `value` — create a TM segment
- `add` with path `/{segmentId}/records/-` and `value` `{ languageId, text }` — append a record to a segment
- `remove` with path `/{segmentId}` — delete a segment
- `remove` with path `/{segmentId}/records/{recordId}` — delete a segment record
- `replace` with path `/{segmentId}/records/{recordId}/text` and a string `value` — update record text

The `200` response returns the collection of updated TM segments.

Note: the single-segment **Edit TM Segment** method (`api.tms.segments.patch`) request body is now formally defined as a discriminated union of add/replace/remove operations with `op` and `path` required — the wire format is unchanged, but generated types may need regeneration.

Client libraries should add the batch method. Available in both Crowdin and Crowdin Enterprise.
