Fix Non-dimensionalization to translation velocity

[rois1995]

Proposed Changes

Problem: When a marker is translating, the translation velocity is not adimensionalized. An adimensional unsteady simulation will diverge after the first iteration.
Fix: add non-dimensionalization of translation velocity in Mesh solver.

• I am submitting my contribution to the develop branch.
• My contribution generates no new compiler warnings (try with --warnlevel=3 when using meson).
• My contribution is commented and consistent with SU2 style (https://su2code.github.io/docs_v7/Style-Guide/).
• I used the pre-commit hook to prevent dirty commits and used pre-commit run --all to format old commits.
• I have added a test case that demonstrates my contribution, if necessary.
• I have updated appropriate documentation (Tutorials, Docs Page, config_template.cpp), if necessary.

Here the problem and the fix are shown:

NACA0012 moving downwards with a certain velocity.

Black line = starting profile
Red line = after one iteration and with dimensional simulation
Blue line = after one iteration and with non-dimensional simulation pre-fix
Green dots = after one iteration and with non-dimensional simulation post-fix
