Add github action to make sure webring builds

[sivakusayan]

This should fix #124.

As an aside, I had to bump the netlify-cli package to get around an EBADPLATFORM issue that would occur when installing the dependencies with npm ci. I hope this is OK, but let me know if it's not and I can try figuring another way around it.

How I tested

I used the act repo to test this action locally, but you can test this in any way you like.

1. Introduce some error in the data/members folder (I just deleted a comma from a random JSON file).
2. Verify that running the GitHub action fails.
3. Remove the error introduced in step 1.
4. Verify that running the GitHub action succeeds.

I think this should be great! Thank you for taking the time to make and test this, it's really appreciated.

Just wanted to say thank you again for adding this functionality. I've added a few new members in and it works like a charm 🙂
