[Doc][Misc] Comprehensive documentation cleanup and grammatical fixes (#8073)

Browse Source 
What this PR does / why we need it?
This pull request performs a comprehensive cleanup of the vLLM Ascend
documentation. It fixes numerous typos, grammatical errors, and phrasing
issues across community guidelines, developer documents, hardware
tutorials, and feature guides. Key improvements include correcting
hardware names (e.g., Atlas 300I), fixing broken links, cleaning up code
examples (removing duplicate flags and trailing commas), and improving
the clarity of technical explanations. These changes are necessary to
ensure the documentation is professional, accurate, and easy for users
to follow.

Does this PR introduce any user-facing change?
No, this PR contains documentation-only updates.

How was this patch tested?
The changes were manually reviewed for accuracy and grammatical
correctness. No functional code changes were introduced.

```bash
vllm serve Qwen/Qwen3-VL-2B-Instruct \
--tensor-parallel-size 2 \
--compilation-config '{"pass_config": {"enable_sp": true, , "sp_min_token_num": 1000}}'
--compilation-config '{"pass_config": {"enable_sp": true , "sp_min_token_num": 1000}}'
```
- `"enable_sp"`: This is the switch for SP. Since SP relies on graph mode, it is not supported in eager mode.
- `sp_min_token_num` (from upstream vllm's `pass_config`): Based on our experiments, when the number of tokens is small (empirical value is less than 1000), SP can actually bring negative benefits. This is because when the communication volume is small, the fixed overhead of the communication operator becomes the dominant factor. SP will only take effect when `num_tokens >= sp_min_token_num`. **The default value is 1000 on Ascend, which generally does not need to be modified.** To customize, use `--compilation-config '{"pass_config": {"enable_sp": true, "sp_min_token_num": 512}}'`. The value will be appended into `compile_ranges_split_points`, which splits the graph compilation range and checks whether the pass is applicable per range.

Without modifying `sp_min_token_num`, the simplest way and recommended way to enable SP is:
