Update MCP server scripts to use config files

[tobiu]

Update the ai:mcp-server-* scripts in tasks/createPackageJson.mjs to include the configuration file arguments.

This ensures the MCP servers launch with the correct local configuration generated in ai/mcp/server/*/config.json.

Changes:

• ai:mcp-server-github-workflow: Add -c ./ai/mcp/server/github-workflow/config.json
• ai:mcp-server-knowledge-base: Add -c ./ai/mcp/server/knowledge-base/config.json
• ai:mcp-server-memory-core: Add -c ./ai/mcp/server/memory-core/config.json
