[Enhancement]: Add --no-commit Recommendation to Prevent Install Failures

[sg-milad]

What would you like us to improve?

When running forge install smartcontractkit/foundry-chainlink-toolkit, the installation fails if the Git working directory has untracked or modified files. The error message suggests either cleaning the Git state or using the --no-commit flag. However, the official documentation does not mention --no-commit, which can confuse new users.

How important it is?

To improve the developer experience, the documentation should explicitly mention using the --no-commit flag when installing dependencies.
