chore(zones): Merge CA-NL-LB and CA-NL-NF into CA-NL

[VIKTORVAV99]

Issue

The data source have these merged so we need to do so as well.
Part of: GMM-197

Description

Merges the zones so we can add a General Purpose Zone Estimation Model for it.

Double check

• I have tested my parser changes locally with poetry run test_parser "zone_key"
• I have run pnpx prettier@2 --write . and poetry run format in the top level directory to format my changes.

Out of curiosity which data source do you have for it merged?

for reference, the split was done in #3092 but then I think the parser was never actually written, I guess because the data source doesn't give a lot of data

We will be using monthly data from https://www.cer-rec.gc.ca that will be processed into hourly values based on local weather patterns and sunset/sunrise. While not as accurate on a hourly level we've decided to do this for all the missing Canadian zones where we are missing data sources. If we can find better data sources for them in the future we will happily use those.
