### Type of issue

Typo

### Description

From https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.options.ivalidateoptions-1.validate?view=net-8.0#microsoft-extensions-options-ivalidateoptions-1-validate(system-string-0), essentialy from https://github.com/dotnet/runtime/blob/c4d7f7c6f2e2f34f07e64c6caa3bf9b2ce915cc1/src/libraries/Microsoft.Extensions.Options/src/IValidateOptions.cs

> Validates a specific named options instance (or all when name is null).

How is this supposed to work? I understand it like that all existing instances of `TOptions` are passed to _validation_ method. One at time. `string? name` parameter serves to validator to reason about `options` values.

I guess for description is wrong. I expect something like

> Validates a specific options instance optionally accompanied by its name for named instance.
