[FEATURE]: Use the ShellCheck to check the source code style

[junghoon-vans]

Description

ShellCheck is a shell script static analysis tool.
This makes it easy to check the code style of the project.

Solution

• Setup it as pre-commit hook to check the source code style of our project.
• Use pre-commit.ci to check the source code style when a git push event occurs.

Alternatives

• Use github actions to check the source code style when a pull request event occurs.

Additional Context

pre-commit.ci does not yet support docker hook.
So, Therefore, I decided not to apply pre-commit.ci.
