Rename the npm package name from 'solid-js' to 'solid' or 'solidjs'

Just a suggestion. I think either of those names are much cleaner. Could be done for solid 2.0?

With 2.0, the package structure is likely to change in any case, hopefully making use of the @solidjs namespace.

I did manage to secure solid about a year ago. Neither solid nor solidjs was available when I created the package. But there is no way to change without losing our npm download history. Which is actually a pretty big deal for momentum. We have been moving official libraries to @solidjs org but I'm still not 100% on what to do with the main package.

If npm download history is a concern, the best time to perform the switch would be as quickly as possible. Imo I think it's possible to do it with the 2.0 release since the tiny pr boost should compensate for any loss of momentum (in the short run).
