fix: resolve cherry-pick conflicts by reverting wrong target

The mechanical cherry-pick in the previous commit landed conflict markers
on version-v4.1.0-rc.2/docs/aztec-nr/api.mdx (a Testnet-labelled snapshot
whose existing name-based logic correctly returns "testnet" for names
containing "rc"). Revert that file to its pre-cherry-pick state — the
v4.2.0 mainnet fix does not apply to the v4.1.0-rc.2 testnet snapshot.

The equivalent change for v4-next is applied to docs-developers in the
next commit.
