Update QuickFIX/J and build configuration

[donovanmuller]

When trying to use this test framework in a project that uses a more recent version of QuickFIX/J, there were incompatibilities with the older version used in this project. This PR updates the QuickFIX/J version used as well as adjustments for more recent Java and Gradle versions.

Changes

1. Version Catalogs Implementation

   • Introduced Gradle version catalogs for better dependency management
   • Centralizes version declarations for improved maintainability
   • Makes dependency updates more consistent across the project

2. QuickFIX/J Core Update

   • Updated QuickFIX/J core dependency to version 2.3.1

3. Java and Gradle Update

   • Updated build configuration to use Java 17+
   • Updated to build with Gradle 8.14+

Hi Donovan, thank you very much for your interest in fix4j-assert.

We've decided to archive this repository, as neither of us use the code anymore, and it needs a bit of a rewrite. Please feel free to run with your changes in your own fork.

Also, I'm not sure if you meant to, but I think you've included all the generated code in your PR.

Cheers,
Ben
