docs(doxygen): disable html copy clipboard

[ReenigneArcher]

Description

This is required for Doxygen >= 1.10.0, although it doesn't affect us because we have a custom header.html where the copy clipboard functionality was removed altogether, in favor of doxygen-awesome-css' clipboard feature.

See: #2765
