## Linked issue
Closes#5374
## Summary
Move .github/scripts to tools/ so they are included in static checking
and testing.
## Steps to reproduce (before)
- Make a formatting/typing error in prepare_release.py and confirm
`ninja check` does not report that.
- Modify test_validate_version.py to fail tests and confirm it's not
caught by ninja check.
## How to test (after)
The scripts should now be included in the checks as the tools/ directory
is already included by the build system.
