fix: switch Go base from bullseye to bookworm (#74)

mayankpande88 · web-flow · commit c078f9f83db3 · 2026-05-12T16:54:19.000+05:30
golang:1.26.3 dropped the bullseye (Debian 11) variant — only alpine,
bookworm (Debian 12), and trixie (Debian 13) variants are published.
release.yml fails for perf and ruby with 'golang:1.26.3-bullseye:
not found'.

Agent has no cgo, so the produced binary is statically linked; runtime
stages (ruby's bitnami/minideb:bullseye, perf's alpine:3.23.4) are
unaffected.
