Add precision validation for estimator pubs to prevent non-positive v… (#2963)

### Summary

Specifying 0 as you precision in the pub level input on the legacy
EstimatorV2 will cause the following server error:
`RuntimeJobFailureError: "Unable to retrieve job result. Error code
1500;`

A guard clause should be added before server submission to throw
`IBMInputValueError: 'The precision value must be strictly greater than
0.'` instead.

This is consistent to specifying 0 as your precision in the run kwarg
level or default options level.

```
qc = QuantumCircuit(2)
qc.h(0)
qc.cx(0, 1)

pm = generate_preset_pass_manager(optimization_level=1, backend=backend)
isa_circuit = pm.run(qc)
isa_obs = SparsePauliOp("ZZ").apply_layout(isa_circuit.layout)

estimator = EstimatorV2(mode=backend)

# precision = 0 on the pub -> accepted by the client, then ZeroDivisionError server-side
job = estimator.run([(isa_circuit, isa_obs, None, 0.0)])
print(job.result())  # job fails: (error 1500)
```
