Vet Center incorrect heading structure in accordions

[laflannery]

Description

At the bottom of all Vet Center pages, there are accordions that come from centralized content and this is causing an incorrect heading structure:

1. The first issue is that all accordion titles should be h3s but for some reason one of them is an h2:
2. Then, within this accordion, there is an alert that has an h2 heading. This should actually be an h4:

I would also make the case that this alert isn't necessary, this content can simply be added as a basic list on the page - putting it within the additional info component is adding additional clicks and complexity that isn't needed.

Acceptance Criteria

• [ ] Update the heading of the "Am I eligible for Vet Center services as a Veteran or service member?" accordion to be an H3
• [ ] Consider removing the alert within this accordion and reformatting the content to reduce cognitive load. Be sure that the heading structure is correct.
• [ ] If the alert is not removed, update the alert title to be an H4
• [ ] Requires accessibility review

I'm moving this back to the backlog because it appears that there is design work that still needs to be done before we can point it.
