`System.MemoryExtensions.Equals` page should mention `MemoryExtensions.SequentialEqual`

[tats-u]

https://learn.microsoft.com/ja-jp/dotnet/api/system.memoryextensions.equals?view=net-6.0#system-memoryextensions-equals(system-readonlyspan((system-char))-system-readonlyspan((system-char))-system-stringcomparison)

If you want to omit comparisonType or apply this method to non-char span types, you have to use SequentialEqual instead.
