[doc] document disabling Stream Load compression via
sink.properties.compress_type (#3638)
## Versions
- [x] dev
- [x] 4.x
- [ ] 3.x
- [ ] 2.1 or older (not covered by version/language sync gate)
## Languages
- [x] Chinese
- [x] English
- [ ] Japanese candidate translation needed
## Docs Checklist
- [x] Checked by AI
- [ ] Test Cases Built
- [x] Updated required version and language counterparts, or explained
why not
- [x] If only one language changed, confirmed whether source/translation
counterparts need sync
## Summary
Since Flink Doris Connector 26.1.0, gz compression is enabled by default
for Stream Load (apache/doris-flink-connector#648). This PR documents
how to disable it:
- Append to the 26.1.0 release note: compression can be disabled by
setting `'sink.properties.compress_type' = ''`.
- Append the same note to the `sink.properties.*` description in the
connector configuration table so users can find it from the main config
docs.
Applied to all four locations: `docs/` (dev EN),
`versioned_docs/version-4.x/` (4.x EN), and the corresponding
`i18n/zh-CN` Chinese translations.
