Don't indent remarks

When remarks get indented by 4 spaces, they're rendered as code blocks. For example, [this PR](https://github.com/dotnet/dotnet-api-docs/pull/7054/files) introduced indentation that caused the remarks to render as code blocks. A customer fixed that in https://github.com/dotnet/dotnet-api-docs/pull/7104. The /// for the remarks is [here](https://github.com/dotnet/runtime/blob/36b6247cc7743dda997e9d671175ddc2b3e030ba/src/coreclr/System.Private.CoreLib/src/System/Runtime/DependentHandle.cs#L15) - perhaps the `` tags are causing the indentation.

将链接的 PR 7054 和 7104 与 DependentHandle.cs 中的三斜线注释进行比较，然后跟踪处理 标签和缩进的 api-docs-sync 转换流程。完成的标准是注释不再增加四个空格的缩进，并呈现为代码块。
