By default, when you install a dependency using forge install, Foundry will automatically create a new Git commit that includes the changes to your project (such as modifications to the foundry.toml file and the addition of the OpenZeppelin contract files in your project directory).
The --no-commit flag modifies this behavior. When you use this flag, Foundry will still install the OpenZeppelin contracts, but it will not automatically create a new Git commit for these changes. This means you have to manually commit the changes to your Git repository if you wish to do so.
The use of --no-commit gives you more control over your Git history and commit messages, which can be useful in certain workflows or for maintaining a clean project history.
foundryup updates foundry, but for some reason the command might not be available on the command line, so run the installation script again, then call it.
