fix: update stage list in stages component

This commit corrects an error the TaskDefinitionStagesComponent by adding
a call to the `renderRows()` method after pushing a new stage to the
`stages` array. This ensures that the table is updated with the new
stage immediately. The change improves the user experience by providing
real-time updates when adding stages to the task definition.
