fix(doc): replace invalid Hook names in doc comment with BeforeInvocationEvent & AfterInvocationEvent

[deepyes02]

Fix(doc): Replaced StartRequestEvent & EndRequestEvent with BeforeInvocationEvent & AfterInvocationEvent respectively in the docstring for api reference documentation

Description

`StartRequestEvent' & 'EndRequestEvent' in the documentation caused some confusion for users. They seem deprecated, and create errors in the code editor when used.

Related Issues

Wrong information appearing in the documentation, causing some confusion, so I fixed it in this update:
https://strandsagents.com/latest/documentation/docs/api-reference/hooks/

Corrected version

from strands.hooks import HookProvider, HookRegistry
from strands.hooks.events import BeforeInvocationEvent, AfterInvocationEvent
# from strands_tools.calculator import calculator

class LoggingHooks(HookProvider):
  def register_hooks(self, registry: HookRegistry) -> None:  
    registry.add_callback(BeforeInvocationEvent, self.log_start)
    registry.add_callback(AfterInvocationEvent, self.log_end)
  
  def log_start(self, event: BeforeInvocationEvent):
    print(f"Request started for {event.agent.name}")
  
  def log_end(self, event: AfterInvocationEvent):
    print(f"Request ended for {event.agent.name}")

agent = Agent(hooks=[LoggingHooks()])

Thanks for this!

Merged even though integ test was failing. This has since been fixed in #785 and will not reoccur in new PRs which have rebased.
