Remove hardcoded version

[balloob]

This removes the hardcoded version number.

I would prefer if we could include the actual version number. So maybe we should have a small build script to create that a file like cat package.json | jq .version

@balloob Could you please try something like this?

The downside of that approach is that we're now shipping the whole package.json for the web version, while we only need a single string from it. We should aim to keep the web packages as lean as possible, as every byte impacts initial loading time.

I see, good point. I'll merge your change as is, then.

A different approach could be that we have a default version containing export const version = "0.0.0" and the build step overwrites this file with the version from package.json before building.
