DAL/Test: check the case attester not in the DAL committee
What
Adds a unit test similar is present in tezt/tests/dal.ml, test slots attestation operation dal committee membership check in lib_protocol/test.
Why
It was not possible to check specifically for the error Dal_data_availibility_attester_not_in_committee, because it is not raised in mempool mode, and the baker would not include the operation in a block. So the error only can be observed in Block_construction mode.
How
Adapt the parameters and add a new bootstrap account with a smaller balance than the other ones such that this new baker is in the TB committee but not in the DAL committee.
Manually testing the MR
CI sufficient.
