Install instructions suggest v3.x

Should be updated to 4.x, no? I would submit a patch, but I'm not sure what versions the other packages need to be.

Feel free to submit a PR, should be 4.x.

Thanks for the quick responses! If someone can point me to the minimum versions for the deps, I'll patch that too. I'm not familiar enough with node to find them apparently

readme on nodebb main repo is more accurate, MongoDB, version 5 or greater or Redis, version 7.2 or greater
