Fix bad reference in node.rb

[first-timers]

Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!

We know that the process of creating a pull request is the biggest barrier for new contributors. This issue is for you 💝

If you have contributed before, consider leaving this one for someone new, and looking through our general help wanted issues. Thanks!

🤔 What you will need to know.

Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.

This issue is to fix a bad reference to node which should have been self -- to fix the display of http://publiclab.org/methods

Hi, I'm looking for a first issue and it looks like this hasn't been worked on in a few months. @MittalS211, do you need any help?

[jywarren]

[jywarren]

Although you may want to start with the changes @MittalS211 has done!

I opened the code and discovered this was already fixed! Checking the history, it appears to have been part of #2621. https://github.com/publiclab/plots2/pull/2621/files#diff-16d89387de9be2711872969affbc5b57L777
