Merge pull request #1063 from jack-w-shaw/JUJU-6223_add_noble_support

#1063

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: #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
