📝 Description

This change enhances the flexibility of the Dot function by making it compatible with various vector types beyond the default Vector type.

Commit Summary:

• Modified the Dot function in the MathUtils class within kratos/utilities/math_utils.h to accept template parameters for the input vectors, allowing the function to handle different vector types (TVector1 and TVector2).
