Create separate validate-tests repository

[jordanpadams]

💡 Description

The validate source codebase is getting massive, and the tests take forever to run. We should slim down our test suite to a small subset of tests, and move the more comprehensive test suite to separate repo. We can then create a new github action to pull and test the more comprehensive test suite.

• [ ] Determine which tests to keep in validate and which should be moved
• [ ] Pull the rest out and move to validate-tests repo
• [ ] Create github action to pull and test with validate-tests repo (maybe require same branch name?)
