update conanfile.py for conan2 (Version: 2.2.0)

[JeetDSharma]

While building rippled and upon running the command:
conan install .. --output-folder . --build missing --settings build_type=Debug

The following error is encountered:
Error while initializing options. The usage of package names cassandra-cpp-driver:shared in options is deprecated, use a pattern like cassandra-cpp-driver/*:shared instead

As conan2 all patterns now, needs "*"

Hence we need to update conanfile.py to -o pkg*:option=value

Environment
Operating System: Ubuntu 22.04.4
Conan Version: 2.2.2
