Modify refined injection CI test for anisotropic ref ratio (#3605)

* Modify refined ijection CI to account for anisotropic ref ratio

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* change n_move based on new dt

* change variable name to be more specific

* Update Regression/WarpX-tests.ini

Co-authored-by: Edoardo Zoni <59625522+EZoni@users.noreply.github.com>

* reset benchmark for RefineInjection because now it uses anisotropic refinement ratio

* add comment to show the formula for n_move

* Reset benchmark of `RefinedInjection`

* Remove wrong benchmark file
