Missing files required to run `gov-sig-build-circuit` in `packages/circom-circuit`

[sakuyacatcat]

What command(s) is the bug in?

make gov-sig-build-circuit

Describe the bug

When I run make gov-sig-build-circuit, the following error is output:

> make gov-sig-build-circuit
circom src/verify-gov-sig.circom --r1cs --wasm --sym -o ./gov-sig-build
invalid output path
previous errors were found
make: *** [gov-sig-build-circuit] Error 1

Therefore, I created a gov-sig-build directory under packages/circom-circuit and ran it again.

> make gov-sig-build-circuit
circom src/verify-gov-sig.circom --r1cs --wasm --sym -o ./gov-sig-build

Node.js v20.5.0
make: *** [gov-sig-build-circuit] Error 1

It reports that packages/circom-circuit/gov-sig-setup/input.json is missing, and upon checking the directory, it indeed does not exist. Meanwhile, a similar make command user-sig-build-circuit uses packages/circom-circuit/user-sig-setup/input.json, which was committed. Therefore, I suspect that packages/circom-circuit/gov-sig-setup/input.json might have been accidentally omitted from the commit.

Additionally, within the same gov-sig-build-circuit command, gov-sig-setup/witness.wtns also appears to be a required file, but I'm unsure if its absence would prevent the command from executing successfully. I've included this in the report for clarity.

Concrete steps to reproduce the bug. If it's able reproduce via testool, please share test_id from jenkins report

1. Check out the develop branch.
2. Move to the packages/circom-circuit directory.
3. Execute Makefile commands in order from the top.
4. Encounter the above error when executing the gov-sig-build-circuit command.
