Pull request overview

This PR enhances the Snowflake semantic views skill by adding guidance for data sampling to better detect joins and relationships between tables. The changes include renaming the skill from snowflake-semanticview to snowflake-semantic-views and adding instructions for sampling data, validating with queries, and improving the workflow steps.

Changes:

• Added data sampling step (step 5) with SELECT DISTINCT queries limited to 1000 rows for discovering relationships and data types
• Added example query syntax (step 10) for validating the final semantic view works correctly
• Renamed the skill from snowflake-semanticview to snowflake-semantic-views in both the SKILL.md name field and README table
• Renumbered subsequent workflow steps to accommodate the new additions
