switch from rollup to vite

[benoitf]

I think we got issues in the past with rollup (with 3rd party dependencies)

we switched extensions to use vite in Podman Desktop, probably this one should be converted as well.

Related to #38, due to rollup image plugin not being able to handle image import.

Tried to switch but whatever I do I always got an error about window module resolution and I could not get past it. I am using the same config for vite from other extensions and the extension built with it fails to load after installation.

After migrating to vite the openid-client prints out message below

Error: Algorithm "sha256"  not supported. supported values: sha1, md5, passthrough
console.<computed> @ VM5:2
(anonymous) @ VM5:2
emit @ VM4 sandbox_bundle:2
onMessage @ VM4 sandbox_bundle:2

Using suggested plugins to bring back 'sha256' digest did not help.

I sent PR above, that addresses only build speed issue and leaves rollup intact.
