Add Tailscale section to securing-your-node.md

[lutr0]

I put together a section to add to "Securing your Node" describing how to install Tailscale.

Sources:

1. https://www.reddit.com/r/rocketpool/comments/rkgyn8/guide_how_to_seamlessly_access_your_rocket_pool/
   (I didn't add the point 8 about global nameservers, I don't know if it's needed)
2. https://tailscale.com/kb/1039/install-ubuntu-2004/
3. https://tailscale.com/kb/1077/secure-server-ubuntu-18-04/

I'm not an expert, so give a good look at it!

I just took a quick look at this, sorry for the delay! In my opinion, I think this is worthy of breaking out into its own page instead of tying it into the security page. I bet it could use some annotated pictures as well. What do you guys think?

Hey @jclapis, thanks a lot for checking it out, I missed the notification.

I can definitely add some images, especially regarding the Tailscale side. I was not sure about how much to go into detail.

I also like the idea of having it in one page, it's one step beyond the standard configuration and it makes sense to have it by itself or in a "bells and whistles" page for the advanced user.

Is it ok if I add the images and I leave to you to add the guide to a new page? I'm not confident about that part

I can take a crack a this one if you want @jclapis, it was on my mind anyways that we should have an independent tailscail section. Will let me use my shiny new docs dev environment more :)

Hey @blinc117, this would be amazing, I wasn't able to complete the task and I'm a bit ashamed of having this still open. From the last discussion with @jclapis in the discord the only remaining points where to have nice screenshots detailing the onboarding process and having this section on a different page.
