Support alias paths on vite

[esteban-url]

Since we've moved to vite as the bundler for the web side, we need to adjust the way we handle the values.

not sure this is the best way to do it, but it does provide support for alias paths and fixes #8666

@dac09 I was thinking that it's maybe a good idea to keep the old implementation for legacy (webpack) projects.

I've added support for both bundlers now. please let me know if there's anything else i might be overlooking.

Hey @esteban-url just to check - why is the ./ required for vite? src/ui should still be working I believe?

[dac09]

Looking good esteban, but couple of things worth discussing:

1. Should we be considering moving to https://vitejs.dev/config/shared-options.html#resolve-alias?
2. What happens for pre-rendered pages here? I think if you are prerendering and using Vite, it may break with this latest change.

Both discussion points, not suggesting we do either just yet

Hey @esteban-url picking this up again.

So I've taken another look at this, and I think maybe the module aliases are broken with prerender (even without the change in this PR).

Any chance you'll have time to take a look again? Totally understand if you're busy! Let me know either way ✌️

Closing this as superceded by #9574

Thank you again esteban!
