feat(examples): Migrates remaining go examples from monorepo

This moves the two examples that weren't moved from the monorepo. This
also adds tests and adds simple smoke tests for each component. I also
modified the examples job to run once per week to ensure things don't go
stale with new versions of `wash`

+# TinyGo HTTP Password Checker
+
+This repository contains a WebAssembly Component written in [TinyGo][tinygo], which:
+
+- Implements a [`wasi:http`][wasi-http]-compliant HTTP handler
+- Uses the [`httpserver` provider][httpserver-provider] to serve requests
+- Can be declaratively provisioned with [`wadm`][wadm]
+
+[wasi-http]: https://github.com/WebAssembly/wasi-http
+[httpserver-provider]: https://github.com/wasmCloud/wasmCloud/tree/main/crates/provider-http-server
+[wadm]: https://github.com/wasmCloud/wadm
+[tinygo]: https://tinygo.org/getting-started/install/
+[wash]:  https://wasmcloud.com/docs/ecosystem/wash/
+
+# Dependencies
+
+Before starting, ensure that you have the following installed:
+
+- The [TinyGo toolchain][tinygo]
+- [`wash`, the WAsmcloud SHell][wash] installed.
+
+# Quickstart
+
+To get started developing this repository quickly, clone the repo and run `wash dev`:
+
+```console
+wash dev
+```
+
+`wash dev` does many things for you:
+
+- Starts the [wasmCloud host][wasmcloud-host] that can run your WebAssembly component
+- Builds this project
+- Builds a declarative WADM manifest consisting of:
+  - Your locally built component
+  - A [HTTP server provider][httpserver-provider] which will receive requests from the outside world (on port 8000 by default)
+  - Necessary links between providers and your component so your component can handle web traffic
+- Deploys the built manifest (i.e all dependencies to run this application) locally
+- Watches your code for changes and re-deploys when necessary.
+
+[wasmcloud-host]: https://wasmcloud.com/docs/concepts/hosts
+
+## Send a request to the running component
+
+Once `wash dev` is serving your component, to send a request to the running component (via the HTTP server provider):
+
+```console
+curl localhost:8000/api/v1/check -d '{"value": "tes12345!"}'
+```
+
+You should see a JSON response like:
+
+```json
+{
+    "valid": false, "message": "insecure password, try including more special characters, using uppercase letters or using a longer password"
+}
+```
+
+## Adding Capabilities
+
+To learn how to extend this example with additional capabilities, see the [Adding Capabilities](https://wasmcloud.com/docs/tour/adding-capabilities?lang=rust) section of the wasmCloud documentation.
+
+# Issues/ FAQ
+
+<summary>
+<description>
+
+## `curl` produces a "failed to invoke" error
+
+</description>
+
+If `curl`ing produces
+
+```
+➜ curl localhost:8000
+failed to invoke `wrpc:http/incoming-handler.handle`: failed to invoke `wrpc:http/[email protected]`: failed to shutdown synchronous parameter channel: not connected%
+```
+
+You *may* need to just wait a little bit -- the HTTP server takes a second or two to start up.
+
+If the issue *persists*, you *may* have a lingering HTTP server provider running on your system. You can use `pgrep` to find it:
+
+```console
+❯ pgrep -la ghcr_io
+4007604 /tmp/wasmcloudcache/NBCBQOZPJXTJEZDV2VNY32KGEMTLFVP2XJRZJ5FWEJJOXESJXXR2RO46/ghcr_io_wasmcloud_http_server_0_23_1
+```
