Frontend: Dialog to present to maintainers to take ownership of pipeline schedule

Problem

As a result of #118782 (closed), currently, we don't allow the ability for maintainers that currently don't have ownership of the pipeline schedule to view or edit it at all.

Proposal

When users attempt to edit the pipeline schedule by clicking on the ✏ icon, they will be presented with a dialog similar to below:

(Title)Take ownership 

Only the owner of a pipeline schedule can make changes to it. Do you want to take ownership of this schedule?


<Cancel> <Take ownership>

If the user chooses Cancel on the dialog, they will be still able to view the edit page but could not make any changes to it.
