fix: Replace prepare with postinstall, since prepare is not supported by yarn

[jacob-lcs]

This pull request includes changes to the package.json file to update the husky dependency and modify the script configuration.

Because yarn doesn't support prepare.

Dependency updates and script configuration changes:

• package.json: Changed the prepare script to postinstall for husky.
• package.json: Updated the husky dependency version from ^9.0.11 to ^9.1.7.
