fix(series): add noble support

[jack-w-shaw]

The pylibjuju client hardcodes a mapping between series codename and the base channel.

Noble was absent from this mapping, meaning pylibjuju doesn't know know to deploy to noble.

Add noble to this mapping.

After noble, we will only support deploying by base. Noble will be the last series added to this map

Fixes: https://github.com/juju/python-libjuju/issues/1062

QA Steps

Download a local charm juju download ubuntu, unzip, and amend the manifest,yaml to support ubuntu@24.04

Place the charm dir at ./ubuntu

You will see

$ cat ./ubuntu/manifest.yaml
bases:
- architectures:
  - amd64
  channel: '20.04'
  name: ubuntu
- architectures:
  - amd64
  channel: '22.04'
  name: ubuntu
- architectures:
  - amd64
  channel: '24.04'
  name: ubuntu

Then:

$ juju bootstrap lxd lxd
$ juju add-model
$ python -m asyncio
>>> from juju.model import Model
>>> m = Model()
>>> await m.connect()
>>> await m.deploy("./ubuntu", series="noble")
<Application entity_id="ubuntu">
>>> exit
(wait)
$ juju status
 Model  Controller  Cloud/Region         Version      SLA          Timestamp
m      lxd         localhost/localhost  3.6-beta1.1  unsupported  12:03:15+01:00

All CI tests need to pass.

[jack-w-shaw]

Yeah this makes sense, let's also add an integration test that deploys a workload on noble, just to catch future regressions about that, because compatibility across versions will be relevant when the 4.0 comes, we don't wanna miss anything there.

Integration test added
