Don't indent remarks

[gewarren]

When remarks get indented by 4 spaces, they're rendered as code blocks. For example, this PR introduced indentation that caused the remarks to render as code blocks. A customer fixed that in dotnet/dotnet-api-docs#7104. The /// for the remarks is here - perhaps the <para> tags are causing the indentation.

Need to tackle this one soon. Been working through the list of issues, and now I'm noticing this one.
