RouteOptions.LowercaseUrls isn't respected

[OskarKlintrot]

Describe the bug

When setting RouteOptions.LowercaseUrls to true this package still uses camel casing.

What area is it related to
API

To Reproduce

Set LowercaseUrls to true:

builder.Services.Configure<RouteOptions>(options =>
{
    options.LowercaseUrls = true;
});

After challenge when /ActiveLogin/BankId/Auth?returnUrl=%2Fal-bankid-auth-samedevice-callback&uiOptions=... is called, it is CamelCase instead of lowercase.

Expected behavior
Request /activelogin/bankid/auth

Screenshots
N/A

NuGet package version
11.0.0

Runtime version
.NET 9

Smartphone (please complete the following information):

• Device: iPhone 8 and 16 Pro
• OS: 16.7.10 and 18.6.2
• Browser: Safari, works on Chrome

Additional context
We use Razor Pages and not MVC. We noticed this when trying to figure out why BankID was launched two time on Safari on iOS. It will get called again but the next time it's lowercase. Not sure yet if it's related.

Now we tested again after reverting back to camel case, now BankID only launches once on Safari. So, if RouteOptions.LowercaseUrls is set to true BankID launches twice on Safari.
