[Bug] Angle bracket escaping is fixed for blocks, but not inline code

[jskeet]

Describe the bug

#2723 was marked as completed via #8596, but I believe that only fixes it for blocks.

To Reproduce
Steps to reproduce the behavior:

In a new project use this code:

namespace Escaping;

/// <summary>Class summary</summary>
public class Library
{
    /// <summary>Inline `&lt;angle brackets&gt;`.</summary>
    public void Method1()
    {
    }

    /// <summary>Block
    ///
    ///     Line before
    ///     &lt;angle brackets&gt;
    ///     Line after
    /// </summary>
    public void Method2()
    {
    }
}

... and this docfx config:

{
  "metadata": [{
    "src": [{ "files": ["*.csproj"]}],
    "dest": "api",
  }],
  "build": {
    "content": [{ "files": ["api/**.yml", "api/index.md"] }],
    "dest": "_site",
    "template": ["default"],
  }
}

Build and serve the file.

Expected behavior

<angle brackets> in both block and inline documentation.

Instead:
