feat(tools): add rss tool to Strands tools repository

[jimbrub]

Description

This PR introduces an RSS feed management tool, enabling agents to interact with RSS feeds for information gathering, content monitoring, and data integration tasks.

This tool provides comprehensive RSS feed management capabilities:

• Fetch: Retrieve feed content from URLs without subscribing
• Subscribe: Add feeds to a subscription list
• Unsubscribe: Remove feed subscriptions
• List: Display all subscribed feeds
• Read: Access entries from subscribed feeds
• Update: Refresh feeds with new content
• Search: Find entries matching specific queries
• Categories: List all categories/tags across feeds

Use cases:

• Automated content aggregation and curation
• Real-time monitoring of news and updates
• Integration of RSS data into other agent workflows
• Content analysis and trend tracking
• This tool can be paired with other tools like HTTP Client for comprehensive web data gathering, or with NLP tools for advanced content analysis

The tool handles RSS-specific operations, reverting to the LLM's capabilities for tasks like summarization or content generation based on feed data
