Set max parallel jobs on Github to a lower value

[simzzz]

Problem

While working on https://github.com/hashgraph/hedera-json-rpc-relay/issues/3353 I noticed tests fail more often when all of them are ran in parallel but when you rerun them manually one by one they almost always pass. It might seem that they are competing for the limited resources that the runner has

The team from solo have a limit for this reason - https://github.com/hashgraph/solo/blob/main/.github/workflows/flow-pull-request-checks.yaml#L95 and implementing a similar limit could improve the flakiness that we are experiencing.

Solution

• Set max-parallel value to 5 or another value
