Add Framework name and version in Sanic instrumentation

Django and Flask integrations have framework name and version extracted from the packages automatically.
This is missing in Sanic integration, it will be very useful as I have a lot of applications running different frameworks and versions.

(I currently use manual config which is not scalable and hard to maintain on upgrade)

[xrmx]

@goodki-d Are you passing a client explicitly when instantiating ElasticAPM? If so you need to use elasticapm.contrib.sanic.utils.make_client that will set framework name and version. The one created by default should contain the framework data already.

Yes I've been creating client object and passing it manually to sanic.ElasticAPM.
Thanks! I couldn't find anything related in docs so I thought the feature was absent
