Update sdk-harness's configurables_in_contract test variable name f…

…rom `CONTRACT_ID` to `MY_CONTRACT_ID` (#6167)

## Description

As described in #6137, the
`configurables_in_contract` test has a `ContractId` defined as
`CONTRACT_ID` in the configurable block. If `forc test` were to be run
on the sdk-harness, it would fail to compile.

Until the compiler explicitly disallows `CONTRACT_ID` in a configurable
block, this configurable has been changed to `MY_CONTRACT_ID`.
