Make the credit card validation alert dismissible

What does this MR do?

This MR makes the credit card validation alert dismissible until the next pipeline run (if there is another error). Also ensures the shared_runners_toggle component dismiss event will dismiss now since it uses the same component.

This change is guarded on the BE by the flag ci_require_credit_card_on_free_plan

How to setup and validate locally (strongly suggested)

• In ee/app/models/ee/user.rb change the requires_credit_card? method locally to return true for testing purposes.
• Then attempt to run a pipeline, dismiss the alert and try to run the pipeline again (you should see the alert again)
• Check that alert is not showing if there is no CC validation error
