Running mypy on SDK resources (following up #3995)

[asasvari]

Description

This PR is a continuation of #3995
Quoting Medinat Lawal:
Part of #1608
Addressing running mypy on opentelemetry-sdk iteratively so we don't have to make one big change addressing all mypy issues at once.

Type of change

• Run mypy against SDK resources

How Has This Been Tested?

• I executed the following tox commands:
  • tox -e mypy
  • tox -e test-opentelemetry-sdk
  • tox -e test-opentelemetry-api
• Ran basic examples (async_context.py, basic_trace.py, logs/example.py) using local changes

Checklist:

• Followed the style guidelines of this project
• Changelogs have been updated
• Unit tests have been added
• Documentation has been updated
