Add minimal getting started doc in Readme

[jkone27]

suggestion, add minimal getting started code docs in readme,
so people can quickly get started without diving deep into other docs or tests or samples

e.g. in fsx, is there a way to make configuration more fluent, like Saturn or Falco? or maybe instead of CE using some adapter functions so configuration can be chained simply with |>

#load "runtime-scripts/Microsoft.AspNetCore.App-latest-8.fsx"
#r "nuget: Oxpecker"

open Microsoft.AspNetCore.Builder
open Microsoft.Extensions.DependencyInjection
open Oxpecker

let endpoints = [
    route "/hello" ("Hello World!" |> text)
    route "/hello-json" ("""{ "Hello": "World!" }""" |> json)
]

let configure (builder: WebApplicationBuilder) =
    builder.Services.AddRouting().AddOxpecker() |> ignore
    builder.Build()

let configureApp (app: WebApplication) =
    app.UseRouting().UseOxpecker(endpoints) |> ignore
    app

let webApp = 
    WebApplication.CreateBuilder()
    |> configure
    |> configureApp

webApp.Run()

@jkone27 Will reference to the Empty example work?
https://github.com/Lanayx/Oxpecker/blob/develop/examples/Empty/Program.fs

As for #load "runtime-scripts/Microsoft.AspNetCore.App-latest-8.fsx" - do you want to contribute it? If yes, you can make a PR and we can add this as example of how to run Oxpecker from script

[jkone27]

sure, i posted an example also for openapi that doesnt seem to work, if u want to try it. opened separate issue, glad to contribute to docs sure

I've added a documentation change, also wanted to comment on this

e.g. in fsx, is there a way to make configuration more fluent, like Saturn or Falco?

You won't believe, but one of the main reasons I created Oxpecker instead of going with Falco or Saturn is that I didn't like their builders approach for configuration :) And it seems to be the right choice, since as far as I know recently Falco got rid of builders as well (even though it was a breaking change).

Closing as starting doc was updated, any work regarding script support should relate to #10
