[doc](upgrade) Fix broken zh-CN versioning link in cluster upgrade docs

[Rango-2017]

Summary

• Chinese cluster-upgrade pages linked to /zh-CN/community/release-versioning, which 404s.
• Point them at /zh-CN/community/release-and-verify/release-versioning, matching the English docs.

Fixes #4006

Test plan

• Confirm https://doris.apache.org/zh-CN/community/release-versioning still 404s
• Confirm https://doris.apache.org/zh-CN/community/release-and-verify/release-versioning loads
• After merge, check the 版本规则 link on 3.x / 4.x / 2.1 / dev Chinese upgrade pages

@morningman these two have been siting since Aug 31 with no review.

#4097 points the zh-CN cluster upgrade "版本规则" link at /zh-CN/community/release-versioning, which 404s. The live page is /zh-CN/community/release-and-verify/release-versioning, same path the English upgrade docs already use.

#4098 is the EXPLODE_SPLIT exmaple for k1 = 5. The query has ORDER BY k1, e1 and k2 is 1,2,3, but the printed rows are 2, 3, 1. Should be 1, 2, 3. Same block in 3.x / 2.1 / 2.0, English and zh-CN. 4.x and current are already sorted.

Happy to trim the scope if 2.0 is out of bounds.
