fix: add missing run_context parameter to pre-hooks and post-hooks reference

[emanuel-braz]

Description

The reference pages for pre-hooks and post-hooks listed session_state, dependencies, and metadata as directly injectable parameters, but the SDK never injects them. These values are only accessible via run_context.session_state, run_context.dependencies, and run_context.metadata.

Additionally, run_context (which is actually injected) was missing from both parameter tables.

This fix removes the three incorrect parameters and adds run_context with a link to the Run Context reference, aligning the reference pages with:

• The overview page (which already correctly lists run_context)
• The SDK code in agno/agent/_hooks.py and agno/team/_hooks.py

Verified against SDK v2.5.0 (commit ddd1292) and current main.
