docs: fix typos and spelling errors across design and user-guide docs

## Summary While going through the Volcano documentation as a new contributor, I came across several clear spelling mistakes and typos across a few design and user-guide files. Fixing these will improve readability for newcomers onboarding to the project. ## Issues Found ### `docs/design/device-sharing.md` | Line | Current Text | Suggested Fix | |------|--------------|---------------| | 59 | `a monitor mothod for debug` | `a monitor method for debug` | | 61 | `Create a seperate package` | `Create a separate package` | | 63 | `const values and definations` | `const values and definitions` | --- ### `docs/design/distributed-framework-plugins.md` | Line | Current Text | Suggested Fix | |------|--------------|---------------| | 125 | `add TF_CONFIG envrionment` | `add TF_CONFIG environment` | | 465 | `mouted to specified path` | `mounted to specified path` | | 532 | `check if the pod is alived` | `check if the pod is alive` | | 574 | `plugin denpendency` | `plugin dependency` | --- ### `docs/design/resource-strategy-fit-scheduling.md` | Line | Current Text | Suggested Fix | |------|--------------|---------------| | 13 | `the scare resources of the node` | `the scarce resources of the node` | | 32 | `utilization of scare resources` | `utilization of scarce resources` | | 96 | `do not have scare resources` | `do not have scarce resources` | --- ### `docs/design/colocation/Overview.md` | Line | Current Text | Suggested Fix | |------|--------------|---------------| | 242 | `offilne worload is evicted` | `offline workload is evicted` | | 283 | `guaranteed by host kernal` | `guaranteed by the host kernel` | | 385 | `coloation is enabled` | `colocation is enabled` | --- ### `docs/user-guide/how_to_use_svc_plugin.md` | Line | Current Text | Suggested Fix | |------|--------------|---------------| | 334 | `such as \`corndns\`` | `such as \`coredns\`` | ## Proposed Fix I will follow this issue with a small focused PR fixing all the items listed above. No paragraph rewrites or reformatting — strictly the errors listed.
