Add urllib3 upper limit to Python auto-instrumentation

[tammy-baylis-swi]

Description:

Adds an upper version limit to urllib3 for Python auto-instrumentation. Python OTLP HTTP exporter depends on requests ~= 2.7 and that depends on "urllib3>=1.21.1,<3". urllib 2.3.0 is the latest and drops support of Python 3.8. We are still supporting Python 3.8.

Link to tracking Issue(s):

• Resolves: Startup errors with autoinstrumentation-python 0.50b #3616
• Short-term patch for: Update autoinstrumentation image builds to support all supported Python versions #3712

Testing: docker build finishes without error.
