Create pipeline schedule tabs component

This issue should be tackled third in the epic after completing #371990 (closed)

Plan

Refactor app/views/projects/pipeline_schedules/_form.html.haml into a Vue component for use in pipeline_schedules_table_app. Where the tabs component and the table component will be inserted into the DOM.

Note

When building the tabs component ensure that the New schedule button is included as well.
