docs(mps_parser): drop Gurobi-specific LP dialect references

Replace the four mentions of Gurobi and their docs URL with a neutral
description: the parser accepts the conventional LP dialect implemented
by most commercial optimization solvers (not the lpsolve variant, which
has a different syntax). Files touched:

- cpp/libmps_parser/include/mps_parser/lp_parser.hpp (public-header
  doxygen)
- python/cuopt/cuopt/linear_programming/cuopt_mps_parser/parser.py
  (ParseLp docstring)
- docs/cuopt/source/cuopt-c/lp-qp-milp/lp-qp-example.rst
- docs/cuopt/source/cuopt-cli/cli-examples.rst

Comment-only change; no behavior impact. PARSER_TEST: 95/95 pass.
