vite: fix docker build (#2738)

## Description:

The sync-assets wasn't executing on docker-build. so instead just import
it from resources/ directory, vite logs a warning but I think that's
okay for now.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
