Add workflow to sync dev branch with next without submodules

[jmborr]

Description of the changes

This PR adds a GitHub Actions workflow to automatically synchronize the dev branch with the next branch while excluding submodules. The workflow ensures that the dev branch remains a clean deployment-ready version of next without test data dependencies.

• Automated sync triggered on pushes to the next branch
• Removes .gitmodules and test data submodules from the synced branch
• Uses force push to maintain branch consistency

Check all that apply:

• updated documentation
• Source added/refactored
• Added unit tests
• Added integration tests
• Verified that tests requiring the /SNS and /HFIR filesystems pass without fail

References:

• Links to IBM EWM items

Check list for the reviewer

• best software practices
  • clearly named variables (better to be verbose in variable names)
  • code comments explaining the intent of code blocks
• All the tests are passing
• The documentation is up to date
• code comments added when explaining intent
