chore(cardano-services): temporarily downgrade chain-history version

openApi 3.1.0 version bump brought only two conway-era specific
Redeemer purpose enum values: "vote" and "propose".
Which makes it backwards compatible to 3.0.1 back-ends.
But the version check does not allow querying 3.0.1 back-ends.
To avoid upgrading deployments just for the sake of accepting
3.1.0 requests, I am temporarily dropping the version back to 3.0.1.
Once all deployments are upgraded to Cardano Node 8.9.2 version,
I will bump this version back to 3.1.0 (LW-10774)
