See #60600 or #69404 for reference.

@carlossanlop - should I port this to dotnet-api-docs manually after merging, or will our process do that?

• The updated documentation refers to the host being 'stopped gracefully', which may conflict with the exception name 'HostAbortedException'. Consider aligning the terminology to avoid potential confusion—either adjust the name or update the wording to better match the intended behavior.

/// The exception that is thrown when an <see cref="IHost"/> is stopped to indicate the Host is stopping gracefully.  This exception should not be thrown or handled by user code.

Microsoft.Extensions.Hosting uses triple slash as source of truth, so you don't need to do anything else. This update will get propagated automatically to the docs repo.

I think this looks good as a description of the exception type itself.
