Fixes #36103 - Address Paginaion issue on ACS Main Table

[parthaa]

What are the changes introduced in this pull request?

ACS Main page was not showing the correct behavior on Select Page/Select None.
This was because the selectedCount was not getting passed.

What are the testing steps for this pull request?

• Setup a bunch of ACS' more than the page size. I used following hammer script

for i in  {1..25}
do 
hammer alternate-content-source create --alternate-content-source-type custom --name "$RANDOM - test" --content-type yum --base-url https://potato.com/ --smart-proxy-ids 1
 done

• Now go to Content -> Alternate Content Sources
• Do a select page (via checkbox)
• Try unselecting

Before PR
Cannot Unselect

After PR
Unselection and other pagination aspects all work.
