Small fixes for chat template

[MackinnonBuck]

Fixes some issues that unblock local development:

1. Add a launchSettings.json file. Without this, the environment defaults to Production and this causes the page to fail to load when running with dotnet run.
2. Fix the TailwindBuild target to always run after the BuildNpmDependencies target. This just required changing the AfterTargets to a DependsOnTargets.

Excellent - thanks!

I don't know how much difference it makes but the ASP.NET Core templates also do something to suppress these kestrelHttp(s)Port parameters from appearing in the CLI: https://github.com/dotnet/aspnetcore/blob/main/src/ProjectTemplates/Web.ProjectTemplates/content/EmptyWeb-CSharp/.template.config/dotnetcli.host.json#L11-L16

If you think it's reasonable to copy that pattern here that's great, but like I say I'm not certain what impact it has.

Yep, seems reasonable to me 🙂
