[Doc] Remove duplicate TOCs during MkDocs migration

[Zerohertz]

This PR removes duplicate table of contents (TOCs) from documentation files as part of the migration to MkDocs.
MkDocs automatically generates navigation and TOCs, making manually written TOCs redundant and potentially conflicting.

• /deployment/nginx.html
  

Original Contents

This pull request makes a small correction to the docs/cli/README.md file.

• Fixing indent for table of contents.
• Fixing hyperlink for the serve section to use an underscore instead of a hyphen for consistency.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Is it necessary to have a table of contents here at all? It just manually duplicates what is on the right:

[Zerohertz]

I think you're right. Would it be better to create a separate branch and submit a PR that removes the table of contents more comprehensively?

[Zerohertz]

Additionally, since the migration to MkDocs, I've found that unordered lists (-) with 2 or 3 space indentation are not rendering properly across many documents.
It would be beneficial to apply a consistent formatting fix for this issue throughout the documentation.

You can do it in this branch, whatever's easiest.

Additionally, since the migration to MkDocs, I've found that unordered lists (-) with 2 or 3 space indentation are not rendering properly across many documents.

This is meant to be enforced by

vllm/pyproject.toml

Line 166 in ebb1ec9

plugins.md007.indent = 4 # ul-indent

but clearly something isn't working properly

[Zerohertz]

Then I'll modify the current PR to remove all TOCs.

Additionally, it would be better if we could delete that line from pymarkdown and find a setting in MkDocs that can recognize indentation with existing spaces as well.

[hmellor]

We should still enforce something standard, but yeah it'd be good if the MkDocs config could be more flexible for cases like this

[Zerohertz]

I have removed all duplicate TOCs. (See the revised content)
