Limited Wasp version to ^16.0.0 && <=16.15.0 (#634)

* Limited Wasp node version to ^16.0.0 && <=16.15.0. In the process, I removed .nvmrc files from generated code and refactored SemanticVersion to follow npm spec. I also updated CI to use node 16.15.0, and not any 16. I also updated docs.

+:::info
+
+Why does Wasp require this specific `node` range and doesn't support a newer version x.y.z?
+
+At Wasp, we focus on supporting the latest LTS ("long-term-support") Node.js version, since it guarantees stability and active maintainance, which is why official Node.js team recommends it for usage in production.
+Therefore, a specific Wasp release will usually require the version of Node.js that was LTS at that point of time.
+Check out https://nodejs.org/en/about/releases/ for more details about Node.js releases.
+
+Sometimes we will make an exception to that and additionaly limit the Node.js version or postpone switching to the latest LTS if there are certain issues with new Node.js version, in which case we will catch up once those are resolved on Node.js side or we find a workaround on Wasp side.
