Instructions for contribution lead to multiple `failed to load module for ssr` errors

[jwsinner]

I've run through the CONTRIBUTING documentation several times now and can't seem to get the site running. After running npm run bootstrap, changing to the package/site directory and running npm run dev the site fails to load with the following errors:

failed to load module for ssr: ./Paper.svelte
Error: failed to load module for ssr: ./Paper.svelte                                                                                                                 
    at instantiateModule ([path to repo]/packages/site/node_modules/vite/dist/node/chunks/dep-6b3a5aff.js:53337:15)
failed to load module for ssr: ./TopAppBar.svelte
Error: failed to load module for ssr: ./TopAppBar.svelte                                                                                                             
    at instantiateModule ([path to repo]/packages/site/node_modules/vite/dist/node/chunks/dep-6b3a5aff.js:53337:15)

I feel like I'm missing something here and really want to contribute, but there always seems to be something preventing me from loading the site to see if the changes I'm making are actually taking.
