Add Survey and Next Steps pages (#524)

Add a Survey page at the end of the training to collect feedback, then a final one with links to further resources. The pages are set up to encourage learners to complete the survey in order to access the next steps, but the Next Steps page is accessible directly from the left hand menu. 

Just doing this for Hello Nextflow for now but if it works well we'll clone this for all other trainings.

+# Next Steps
+
+Congrats again on completing the Hello Nextflow training course and thank you for completing our survey!
+
+**Here are our top 3 recommendations for what you can do next to take your Nextflow skills to the next level.**
+
+### 1. See how what you just learned applies to a scientific analysis use case
+
+**Check out the [Nextflow for Science](../nf4_science/index.md) page** for a list of short standalone courses that demonstrate how to apply the basic concepts and mechanisms presented in Hello Nextflow to common scientific analysis use cases.
+
+If you don't see your domain represented by a relatable use case, let us know in the [Community forum](https://community.seqera.io/) so we can add it to our development list.
+
+### 2. Delve into the details
+
+In the Hello Nextflow course, we keep the level of technical complexity low on purpose to avoid overloading you with information you don't need in order to get started with Nextflow.
+As you move forward with your work, you're going to want to learn how to use the full feature set and power of Nextflow.
+
+To that end, we are currently working on a collection of Side Quests, which are meant to be short standalone courses that go deep into specific topics like testing, metadata handling, using conditional statements and the differences between working on HPC _vs._ cloud.
+
+In the meantime, feel free to **browse the [Fundamentals Training](../basic_training/index.md) and [Advanced Training](../advanced/index.md)** to find training exercises about the topics that interest you.
+
+### 3. Learn how to use nf-core resources and the Seqera Platform
+
+**The [nf-core project](https://nf-co.re/) is a worldwide collaborative effort to develop standardized open-source pipelines for a wide range of scientific research applications.**
+It includes [over 100 pipelines](https://nf-co.re/pipelines/) that are available for use out of the box and [well over 1400 process modules](https://nf-co.re/modules/) that can be integrated into your own projects, as well as a rich set of developer tools.
+
+**[Seqera Platform](https://seqera.io/) is the best way to run Nextflow in practice.**
+It is a cloud-based platform that you can connect to your own compute infrastructure to make it much easier to launch and manage your workflows.
+The Free Tier is available for free use by everyone (with usage quotas).
+Qualifying academics can get free Pro-level access (no usage limitations) through the [Academic Program](https://seqera.typeform.com/to/SRB8Ci3n).
+
+We are currently developing a short training course demonstrating how to use both of these resources (either independently or in combination).
+In the meantime, check out the [nf-core docs](https://nf-co.re/docs/) and the [Seqera Platform tutorials](https://docs.seqera.io/platform/latest/getting-started/quickstart-demo/comm-showcase)
+
+### That's it for now!
+
+**Good luck in your Nextflow journey and don't hesitate to let us know in the [Community forum](https://community.seqera.io/) what else we could do to help.**

+# Feedback survey
+
+Before you move on, please complete this short 4-question survey to rate the training, share any feedback you may have about your experience, and let us know what else we could do to help you in your Nextflow journey.
+
+This should take you less than a minute to complete. Thank you for helping us improve our training materials for everyone!
