chore(githooks): add pre-commit script to sync solc version

This commit adds a new pre-commit script called "pre-commit-solc-sync" to the githooks directory. The script is responsible for extracting the solc version from the "foundry.toml" file and updating the ".vscode/settings.json" file with the extracted version. If the "solidity.compileUsingRemoteVersion" key already exists in the settings file, the script updates the version. Otherwise, it modifies the last key, adds the new key, and closes the JSON object. Finally, the updated settings file is added to the commit.

The purpose of this change is to automate the synchronization of the solc version used for Solidity compilation in the project everywhere else its also need to be configured configured.
