Fix incorrect validation error

[gndelia]

While developing on Hemi, I came across this incorrect error message:

minDecimals should be smaller than maxDecimals, but the error message states otherwise. This PR fixes the error message + the test

[Copilot]

Pull Request Overview

This PR fixes an incorrect validation error message in the smart-round library. The error message previously stated that "minDecimals should be larger than maxDecimals" when the validation actually checks if minDecimals is greater than maxDecimals, which should be an invalid condition.

• Updates the error message to correctly state "minDecimals should not be larger than maxDecimals"
• Updates the corresponding test description and expected error message to match the corrected validation
• Bumps the package version from 3.0.0 to 3.0.1
