Before, flow/scripts/variables.json was still tracked after #4800, a 1,623-line copy of variables.yaml that nothing used and that went stale with every variables.yaml change.
Now, it is deleted, and variables.yaml is the only variable list.

Why it was left behind: #4800 moved defaults.py and non_stage_variables.py onto variables.yaml and removed yaml_to_json.py and the CI sync check, but kept the JSON to avoid conflicts while in review, with its deletion promised as a separate PR. This is that PR.

Checked: on master, git grep outside the tools/ submodules for variables.json, yaml_to_json, and JSON reads in scripts, *.mk, flow/Makefile, .github workflows, docs, tests, docker/etc, .gitignore and .gitattributes: nothing reads, generates or checks the file.

and removed yaml_to_json.py and the CI check that kept the JSON in
sync, but left the JSON itself in place to avoid conflicts while it was
in review. Nothing reads, generates or checks it any more.

This pull request deletes the JSON configuration file containing definitions, descriptions, and stage associations for various OpenROAD flow variables (such as ABC_AREA, ABC_DRIVER_CELL, and SYNTH_ARGS). There are no review comments, and I have no feedback to provide.
