Revise and expand Computer config docs (CN/EN)

Rewrite and restructure the Computer configuration documentation in both Chinese and English. The changes replace the old flat option tables with organized sections (Basics, Algorithm, Input, Snapshot/Storage, Worker/Master, I/O/Output, Network/Transport, Storage, BSP, Performance, System-managed, K8s Operator, KubeDriver and CRD). Added clear default-value semantics, examples for local and MinIO snapshots, notes about system-managed options (do not modify), and more explanatory text for many options. Also updated related CRD/KubeDriver fields formatting and clarified operator environment variable mapping. Minor related updates applied to the quickstart computing hugegraph-computer page.
