Remove build.commonjsOptions.ignore from vite.config.ts

[Peeterush]

Digging into #119 I found that Vite has changed the way it handles the dependencies in question from version 4 and up for both building and consuming.

• For consuming: in version 4 and up you seem to need ws in your own project to be able to build when using this library. Maybe version 3 supplied projects with the ws that Vite uses itself?
• For building: Vite will now automatically externalize the build in modules, and also seems to have a solution for ws.

Taking advantage of these changes by removing build.commonjsOptions.ignore seems to resolve both #119 and also remove the need to install ws in consuming projects.
