API Admin Key Creation

[There seems to be a discrepancy between the documentation and the actual behavior of the system](https://github.com/elsa-workflows/elsa-studio/issues/28). When following the steps outlined in the [Elsa-Server documentation](https://v3.elsaworkflows.io/docs/installation/elsa-server) to set up an Elsa server, the step to create a new admin results in a 401 Unauthorized error. This is unexpected as the documentation mentions that requests from localhost should be allowed.

The request in question is:
```
curl --location 'https://localhost:5001/elsa/api/identity/applications' \\
--header 'Content-Type: application/json' \\
--data '{
"name": "Postman",
"roles": ["admin"]
}'
```

Additionally, the provided `Program.cs` configuration is as follows:
```
using Elsa.Extensions;
using osisa.SmartWeb2.Api.Workflows;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();
builder.Services.AddElsa(elsa =>
elsa
// Configure identity so that we can create a default admin user.
.UseIdentity(identity =>
{
var configuration = builder.Configuration;
var identitySection = configuration.GetSection("Identity");
var identityTokenSection = identitySection.GetSection("Tokens");

identity.IdentityOptions = options => identitySection.Bind(options);
identity.TokenOptions = options => identityTokenSection.Bind(options);
identity.UseConfigurationBasedUserProvider(options => identitySection.Bind(options));
identity.UseConfigurationBasedApplicationProvider(options => identitySection.Bind(options));
identity.UseConfigurationBasedRoleProvider(options => identitySection.Bind(options));
})

// Use default authentication (JWT + API Key).
.UseDefaultAuthentication(auth => auth.UseAdminApiKey())

// EXPOSE API ENDPOINTS
.UseWorkflowsApi()

// REGISTER WORKFLOWS AS HTTP ENDPOINTS under /workflows/{name}
.UseWorkflowRuntime(
runtime => runtime
.AddWorkflow())
.UseHttp()
);

// Configure CORS to allow designer app hosted on a different origin to invoke the APIs.
builder.Services.AddCors(cors => cors.AddDefaultPolicy(policy => policy.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod()));

var app = builder.Build();

// Configure the HTTP request pipeline.
app.UseHttpsRedirection();
app.UseAuthorization();
// ENABLE CORS
app.UseCors();
// ENABLE AUTHENTICATION
app.UseAuthentication();
// ENABLE WORKFLOWS API
app.UseWorkflowsApi();
// REGISTER CONTROLLERS AS HTTP ENDPOINTS
app.MapControllers();
// ENABLE WORKFLOWS TO BE USED AS HTTP ENDPOINTS
app.UseWorkflows();
app.Run();
```

It would be beneficial for users if the documentation could be updated to reflect the correct steps or provide additional troubleshooting steps for this issue.
