Update bootstrap_gen to detect GenAI libraries with instrumentations

What problem do you want to solve?

New/Migrated OTel Python GenAI instrumentation libraries were just released 🎉

It would be nice if opentelemetry-bootstrap --action=install could install them too if corresponding frameworks are installed in current environment, while using the distro. This idea has come up a couple times in the Python SIG meetings but I don't think a ticket was created.

Describe the solution you'd like

Update bootstrap_gen to detect GenAI libraries with instrumentations, and install instrumentations accordingly. What's been migrated so far are:

1. opentelemetry-util-genai==1.0b0
2. opentelemetry-instrumentation-google-genai==1.0b1
3. opentelemetry-instrumentation-genai-openai-agents==1.0b0
4. opentelemetry-instrumentation-genai-openai==1.0b0
5. opentelemetry-instrumentation-genai-langchain==1.0b0
6. opentelemetry-instrumentation-genai-anthropic==1.0b0

Current bootstrap does install these but they should be removed as they follow the "old" Python naming and are published from old home contrib repo:

pip install opentelemetry-instrumentation-google-genai
pip install opentelemetry-instrumentation-langchain

Describe alternatives you've considered

It is currently up to users to install individual instrumentation libraries, from OTel and from OpenLLMetry.

Tip

No response

Start with opentelemetry/instrumentation/bootstrap_gen.py and trace the --action=install flow, including how it detects installed frameworks and selects the distro. Compare the current Google GenAI and LangChain handling with the six migrated GenAI libraries listed in the issue. Done means bootstrap installs the corresponding migrated instrumentations and no longer installs the old-naming packages.
