fix: indent multi-line descriptions in generated docs

[SamMorrowDrums]

Summary

This PR fixes the formatting issue where multi-line tool parameter descriptions break out of the markdown list structure in the generated README documentation.

Fixes #1494

Rendered

Problem

When tool parameter descriptions contain newlines (like the method parameter in pull_request_read), the continuation lines were not indented, resulting in broken markdown rendering:

Before:

  - `method`: Action to specify what pull request data needs to be retrieved from GitHub. 
Possible options: 
 1. get - Get details of a specific pull request.
 2. get_diff - Get the diff of a pull request.
...
 (string, required)

This renders poorly because the continuation lines are not part of the list item.

Solution

Added an indentMultilineDescription() helper function that adds 4-space indentation to all lines after the first line in a description. This maintains proper markdown list formatting.

After:

  - `method`: Action to specify what pull request data needs to be retrieved from GitHub. 
    Possible options: 
     1. get - Get details of a specific pull request.
     2. get_diff - Get the diff of a pull request.
...
     (string, required)

Changes

• cmd/github-mcp-server/generate_docs.go: Added indentMultilineDescription() helper and integrated it into parameter documentation generation
