upgrade_lts_contract.py exception on impish and later

[Grant Orndorff]

[Impact]
When users are upgrading their machines, we run the upgrade_lts_contract script to ensure that the services that were enabled will keep being enabled in the new ubuntu release the users are upgraded to.

Currently, if the user upgrades directly from Focal to Jammy, the script will error out because we are missing the entries for Focal and Impish on that script.

Therefore, even though we might not have full support for some services in Jammy yet, we should not error out on that script and allow it to complete;

[Test Case]
To reproduce the bug: follow these steps:

1. Launch a jammy machine
2. Attach to a valid UA token
3. run `sudo python3 /usr/lib/ubuntu-advantage/upgrade_lts_contract.py`

And to verify that the fix works:

1. Upgrade UA to version 27.8
2. re-run `sudo python3 /usr/lib/ubuntu-advantage/upgrade_lts_contract.py` and confirm no errors are raised

[Regression Potential]
We are just adding the new releases into our support dict and providing better error messages if that problem happens again in the future. Therefore, we don't believe we have a big regression issue here.

[Original Description]

See this error https://errors.ubuntu.com/problem/864d1a4d38167a7b009ce993125030b58eb012d5

When upgrading from focal -> impish or from impish -> jammy, a KeyError will occur in the upgrade_lts_contract.py script from ubuntu-advantage-tools. This happens because that script has not been kept up-to-date with new ubuntu series names since groovy.

We plan to fix this bug in our next release of ubuntu-advantage-tools, which will be version 27.8 and should occur within the next month.

I have tested the package in -proposed using the steps in the description. I first verified the bug occurred on jammy with the current package and that it no longer occurred after upgrading to the package in -proposed. Please see the attached log.

It doesn't look like this bug was captured by the normal automation for the impish SRU of ubuntu-advantage-tools 27.8, but I have performed the verification and the fix works as expected. Please see the attached log.
