fix: Correct mcp_config_file parameter to mcp_config in issue-triage workflow (#89)

The workflow was using 'mcp_config_file' which is not a valid parameter for
the claude-code-base-action. The correct parameter name is 'mcp_config' as
defined in the action.yml file.

This fix ensures that the MCP server configuration is properly passed to the
action, allowing the GitHub MCP server to be correctly initialized.
