Docs: no default value displayed on input-main page

[Cstandardlib]

Details

Now the Default for some input parameters is not displayed on input-main documentation.
For example ks_solver has the default value:

• Default:
  • PW basis: cg.
  • LCAO basis:
    • genelpa (if compiling option USE_ELPA has been set)
    • lapack (if compiling option ENABLE_MPI has not been set)
    • scalapack_gvx (if compiling option USE_ELPA has not been set and compiling option ENABLE_MPI has been set)
    • cusolver (if compiling option USE_CUDA has been set)

but now this part is missing.
