Respect the case of the asp-page parameter value supplied to the anchor tag helper

[mikebrind]

The anchor tag helper ignores the case of the value applied to the asp-page parameter and always capitalizes it when it is rendered.

<a asp-page="page">Click</a> renders as <a href="/Page">Click</a> so does <a asp-page="PAGE">

IMO, it should respect the casing of the provided value, as with the controller, action etc attributes.

Routing in general is case-insensitive, so there are no plans to change this behavior.

There is a routing setting to make all URLs lowercase, if that's all you need: https://github.com/aspnet/Routing/blob/032bcf43b2cefe641fc6ee9ef3ab0769024a182c/src/Microsoft.AspNetCore.Routing/RouteOptions.cs#L15
