Add links to more NestedText implementations?

[erikw]

While I was browsing GitHub I discovered two more implementations that are currently not listed at https://nestedtext.org/en/latest/related_projects.html,

• https://github.com/CoolMineman/nestedtext-java
• https://github.com/dolow/nt-go

that both pass the official tests. Maybe those can be included in the Related Projects page as well?

They have not reached out to me yet. Perhaps they are not ready yet. I will reach out to them and see if they would like to go into the list. Thanks!

I reached out, but neither responded. Perhaps when they get further along.
