PYTHON-4238 - Add Beanie version to handshake metadata

[NoahStapp]

This PR implements MongoDB's wrapping client library specification for the connection handshake to allow library details to be included in the metadata written to mongos or mongod logs.

For example, this change would allow server-side logs such as the following:

{
"t":{"$date":"2025-01-27T23:10:40.108Z"},"s":"I","c":"NETWORK","id":51800,"ctx":"conn16235","msg":"client metadata","attr":{"remote":"127.0.0.1:1094","client":"conn16235",
"doc":{"driver":{"name":"python|beanie","version":"4.15.0|BEANIE_VERSION"},"platform":"Python 3.13.7",
"os":{"name":"linux","architecture":"x64","version":"5.15.133+","type":"Linux"}}}
}

For anyone hosting clusters with connections coming from different applications this can help differentiate connections and facilitate log analysis.
