fix: [jaspr_riverpod] vsyncOverride is missing a variable

[gadfly361]

Description

When trying to run the examples/flutter_embedding example, get the following error:

Steps To Reproduce

1. Clone jaspr repo (this Issue was made against the commit: 3495cfd0693fed99a34ffec0f9f0b8ac9bbfb18e)
2. cd examples/flutter_embedding
3. install dependencies
4. jaspr serve

Expected Behavior

For the flutter_embedding example to have been served to localhost:8080 without hitting an error.

Additional Context

I think this commit may have introduced the regression.

[schultek]

This actually comes from a change in riverpod, where vsyncOverride was removed in the latest version: https://github.com/rrousselGit/riverpod/pull/3072

So we definitely need to fix this, but we also need to update the version constraint for riverpod.

@schultek Thanks for finding the root cause! I updated #139 accordingly
