Rename exercises dir

Name it instead "topics" so it won't be strange if some topics included "exercises" directory.

+# Create Images on The Fly
+
+## Requirements
+
+Have at least one image locally (run `podman image ls` to confirm).<br>
+If you don't have images locally, run simply `podman pull nginx:alpine`.
+
+## Objectives
+
+1. Run a container using a web server image (e.g. httpd, nginx, ...)
+  - Bind container's port 80 to local port 80
+  - Run it in detached mode
+  - Name should nginx_container
+2. Verify the web server runs and accessible
+3. Create an HTML file with the following content and copy it to the container to the container to path where it will be accessed as an index file
+
+```
+<html>
+<head>
+<title>It's a me</title>
+</head>
+<body>
+<h1>Mario</h1>
+</body>
+```
+
+4. Create an image out of the running container and call it "nginx_mario"
+5. Tag the container with "mario" tag
+6. Remove the original container (container_nginx) and verify it was removed
+7. Create a new container out of the image you've created (the same way as the original container)
+8. Run `curl 127.0.0.1:80`. What do you see?
+9. Run `podman diff` on the new image. Explain the output
