Added missing word "be" in prompt instructions.
This is unlikely to change the agent functionality in most cases, but
optimal clarity in prompt language is a best practice.
Thanks to awesome example `research_bot`
Fix andproduce and goodgrammar (and so on)
```python
>>> from examples.research_bot.agents import search_agent
>>> print(search_agent.INSTRUCTIONS)
You are a research assistant. Given a search term, you search the web for that term andproduce a concise summary of the results. The summary must 2-3 paragraphs and less than 300words. Capture the main points. Write succinctly, no need to have complete sentences or goodgrammar. This will be consumed by someone synthesizing a report, so its vital you capture theessence and ignore any fluff. Do not include any additional commentary other than the summaryitself.
