Improve micromamba transaction message (#2474)

* fix: improve transaction message by giving runnable commands back

* misc: extend gitignore with cmake file generated by default when developing in jetbrains clion

* fmt: clang-format using pre-commit

* fix: move the executable back to just mamba or micromamba

* Use new context struct for prefix
