Fixes #36712 - Add true select all to errata legacy UI

[chris1984]

What are the changes introduced in this pull request?

• Adding a select all option in the errata legacy UI when you start to select errata on the table

Considerations taken when implementing this change?

• It looks like Bastion does not keep track of records selected when switching pages in the pagination on multiple pages so this is as close to fixing it as I can. I can raise a Redmine issue to try and fix the other areas, but outside of the scope of this PR

What are the testing steps for this pull request?

• Sync some repos that have errata in them
• Goto content - Errata and select a few and see if the new select all works
• Change the tab to the next table page and make sure they are all selected still
• Click apply and see if it takes you to the next screen without an error
