non static member shadows

When compiling with clang 19.1.7 on Alma with -Werror and a number of other flags (we run with most warnings enabled), the line https://github.com/boostorg/program_options/blob/develop/include/boost/program_options/parsers.hpp#L162 was flagged with `error: non-static data memeber 'm_desc' of 'basic_command_line_parser' shadows member inherited from type 'cmdline' [-Werror, -Wshadow-field]`. We opted to add a local patch to suppress this using pragma push/pop at the above location. Someone with more familiarity with the code may have a more appropriate solution. If the push/pop is the desired solution, happy to submit a PR with that change included.

Env:
Alma 9.6
Boost 1.88.0 via cmake
clang 19.1.7

Inspecciona include/boost/program_options/parsers.hpp alrededor de la línea 162, donde clang 19.1.7 informa de la advertencia de ocultación de un miembro heredado para m_desc. Reproduce la advertencia en Alma 9.6 con Boost 1.88.0 y los indicadores de advertencia indicados, y confirma que el cambio elegido elimina el error -Wshadow-field sin cambiar el comportamiento del análisis de la línea de comandos.
