chore(codeowners): assign infra tree

[kristinapathak]

TL;DR

Route every path below /infra/ to the Infrastructure team.

Additional Details

The prior rule matched only /infra/cassandra/, leaving new infrastructure paths to the default owners. This expands the existing routing rule without changing ownership of current paths.

For the Reviewer

Review .github/CODEOWNERS.

For QA

Ran git diff --check.

QA is not needed for this ownership-only metadata change.

Closes #666
