Description of problem:
Content View filter creation/edit button should say "Save" instead of "Edit rule"
This is a request to change the current text seen in the button to submit/save changes made to content view rules from "Edit rule" to "Save" or "Submit" or "Apply". The current text provides confusion as to what will happen to the changes made on the screen and if they will be applied.

Version-Release number of selected component (if applicable):
Satellite 6.12

How reproducible:

Steps to Reproduce:
1. Login to Satellite Web UI -> Content -> Content View
2. Filters -> Errata - by date range -> Create Filter
or
2. Filters > RPM > Add RPM Rule or Edit existing RPM rule
3. Show "Edit rule" Button

Actual results:
Shows "Edit rule" Button while trying to Edit/Save a rule

Expected results:
"SAVE" button is more logical than "Edit rule" Button in UI

Additional info:
Just a UI/UX RFE, however at the backend it doing the same thing
