[Need help] :sparkles: Add Ensure that spotlessApply is executed before commit

[Corvus400]

Issue

• Nothing.

Overview (Required)

• I have tried to run spotlessApply as appropriate at commit time because I often finally realize that I have not run spotlessApply after a failed CI check.
  • However, this is incomplete because the content of this PR will eventually make it impossible to commit without manually fixing the problem if the number of lines exceeds 100.
  • Also, it is difficult to understand why it cannot be committed, which is likely to confuse developers.
  • Therefore, I would like to make it so that if the line count check fails, the file is automatically formatted, but I have not been able to figure out how to solve this problem myself.
  • I need your help.

Usage

• Execute the following command in the root directory of the project

./scripts/setup_pre-commit.sh
