edge channel stricter about build-environment types in parts

[lengau]

Bug Description

The edge channel can no longer build charmcraft due to a value error in parts.spread.build-environment

To Reproduce

1. Clone charrmcraft (I'm on commit 0d3b27136fb9c21e6d7c091dc4ca4ac6bfee3aca)
2. snapcraft pack with snapcraft revision 12433 (8.3.2.post34+git655e543a)

Environment

KDE Neon noble

snapcraft.yaml

https://github.com/canonical/charmcraft/blob/0d3b27136fb9c21e6d7c091dc4ca4ac6bfee3aca/snap/snapcraft.yaml#L187

Relevant log output

lengau@ratel:~/Work/Code/charmcraft-2$ snapcraft pack
Bad snapcraft.yaml content:
- Value error, value must be a list of Annotated: [{'CGO_ENABLED': 0}] (in field 'parts.spread.build-environment')                                                              
Full execution log: '/home/lengau/.local/state/snapcraft/log/snapcraft-20240815-165625.696525.log'

Additional context

Changing the value of CGO_ENABLED from 0 to "0"resolved it

This likely broke due to pydantic 2 dropping this behavior by default: https://docs.pydantic.dev/dev/api/config/#pydantic.config.ConfigDict.coerce_numbers_to_str

Snapcraft probably needs fixes in places like this:

snapcraft/snapcraft/models/project.py

Line 945 in 037c230

build_environment: Grammar[list[SingleEntryDict[str, str]]] | None = None

Craft-parts probably needs fixes too: https://github.com/canonical/craft-parts/blob/7ea8655b596b359e8542d171bea011f672e1c996/craft_parts/parts.py#L67

Thanks @mr-cal - I've made an upstream PR for it. Once that's merged an update will fix this.
