chore(rb): re-pin staging web2/web3 images to git-a5db7f0

c3da22f0 (previous pin, #3518) failed to build every service except
league-reward-worker — other Dockerfiles didn't COPY the new workspace's
package.json, so `bun install --frozen-lockfile` failed and those images were
never pushed. petpop !1251 fixed the Dockerfiles; a5db7f0 is its develop merge
where all build:* jobs succeed. Bump all staging web2/web3 image tags to
git-a5db7f0afb... so every service (incl. mail-send-worker) resolves.
