[conan 2.0] conan remote add documents option --insert instead of --index

[n-morales]

There is a small mismatch in the documentation for conan remote add and the help output of the command in conan 2.0. It looks like --insert was changed to --index in the 2.0 release but the documentation wasn't updated
