chore: Add team-ai-sme as Dockerfile co-owner

[SaintPatrck]

🎟️ Tracking

No tracking issue; follow-on to #219, which set @bitwarden/team-ai-sme as this repo's default owner.

📔 Objective

We own this repo but hold no review claim on its **/Dockerfile, so the container image we publish can change without anyone on our team seeing it. Adding us alongside team-appsec and dept-bre leaves both existing gates intact and gives us visibility into the image that ships under our name.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This is a one-line .github/CODEOWNERS change that reassigns **/Dockerfile from @bitwarden/team-appsec and @bitwarden/dept-bre to the repo's default owner @bitwarden/team-ai-sme. I verified the description's premise: Dockerfile is the only docker-related file that actually exists in the repo, so the remaining .dockerignore, entrypoint.sh, and docker-compose.yml entries match nothing and this is indeed the last real path owned outside the team. No code, workflow, or dependency changes accompany it. The one question below is about team sign-off, not about the change being wrong.

Code Review Details

• ❓ : Removes team-appsec and dept-bre from the review path for the published container image; CODEOWNERS is self-owned, so those teams are not required to approve their own removal
  • .github/CODEOWNERS:11

@withinfocus are you thinking this should be co-owned, or only under @bitwarden/team-ai-sme?

[withinfocus]

I think that you should list your team alongside the existing owners for this file, so you can self-manage.
