Fix ordering in github-events function deploy (#361)

* Fix ordering in github-events function deploy

In this sample app we ask the user to deploy the application
(function.yaml) before creating the githubsecret. This causes the deploy
to fail with a configerror because it references a secret which doesnt
exist.

* remove typo

 ## Building and deploying the sample
 
-1.  Use Docker to build the sample code into a container. To build and push with
-    Docker Hub, run the following commands, replacing `{username}` with your
-    Docker Hub username:
-
-    ```shell
-    # Build the container on your local machine
-    # Note: The relative path points to the _root_ of the `knative/docs` repo
-    docker build -t {username}/github-events --file=Dockerfile ../../../
-
-    # Push the container to docker registry
-    docker push {username}/github-events
-    ```
-
-1.  After the build has completed and the container is pushed to Docker Hub, you
-    can deploy the function into your cluster. **Ensure that the container image
-    value in `function.yaml` matches the container you built in the previous
-    step.** Apply the configuration using `kubectl`:
-
-    ```shell
-    kubectl apply -f function.yaml
-    ```
-
-1.  Check that your service is running using:
-
-    ```shell
-    kubectl get ksvc -o "custom-columns=NAME:.metadata.name,READY:.status.conditions[2].status,REASON:.status.conditions[2].message"
-    NAME              READY     REASON
-    legit             True      <none>
-    ```
-
-    > Note: `ksvc` is an alias for `services.serving.knative.dev`. If you have
-      an older version (version 0.1.0) of Knative installed, you'll need to use
-      the long name until you upgrade to version 0.1.1 or higher. See
-      [Checking Knative Installation Version](../../../install/check-install-version.md)
-      to learn how to see what version you have installed.

 1.  Create a [personal access token](https://github.com/settings/tokens) to

     GitHub API. Also decide on a token that your code will use to authenticate

     org/repo of your choosing. Note that the personal access token must be valid
     for the chosen org/repo.
