Elsa2: Update Rebus + Jint to latest versions

## Enhancement Request

### Enhancement Overview

#### Jint
Currently Jint is on a beta version 3.0.0-beta-2037 which even if moved to the non beta 3.0.0 it does not compile as the api changed before beta closed.
The latest version is 4.9.2 which changes the Parser from Esprima to Acornima.

#### Rebus
Rebus is also outdated being on version 8.7.1.
The latest is version 8.9.2 which brings .net10 support with it which Elsa support already so should have been updated already.

Update both packages to the versions mentioned above to take advantage of bug fixes and features.
