ci: build beta/algorithm-dpi against algorithm connect/sdk

Point the beta CI workflow's connect clone and sdk checkout at
beta/algorithm-dpi instead of beta/custom-server, and add
beta/algorithm-dpi as a triggering branch, so the new parallel
development line builds against its own connect/sdk branches. No
behavior change to the build itself.
