chore(ci): fix backwards compat tests

[kwannoel]

I hereby agree to the terms of the RisingWave Labs, Inc. Contributor License Agreement.

What's changed and what's your intention?

Broken in #15356. In older version of RisingWave, risedev will try to find the individual binaries for meta-node etc... so we just include that config to make sure it is linked, if it's in a older version.
