chore(web-client): fix default comlink import in node

[onmax]

What's in this pull request?

The current import does not work and when we try to use web client in node will result in an error.

comlink does not have export default, and instead we should use import * as Comlink from 'comlink' like we do in other files. For example bundle.js

I'm using NodeJS v20, and for me the example in web-client/example/node works as is:

• Apply the revised build command from Fix instructions to build web-client for running the example #3282
• If trying on latest albatross branch, apply fix from Fix initialization in NodeJS environments #3281 - not needed if trying with latest tag or before

Can you please try out the example (run index.mjs) and report if it works with your Node version?

If it does, let me know in which context and how you are using the lib in Node that doesn't work.

I get this error when running maxi@Maxi:~/nimiq/core-rs-albatross/web-client$ ./scripts/build.sh --only nodejs,types.

Do I need to compile something before running ./script/build.sh?
