Issue body
### Bug Description
https://bugs.launchpad.net/snapcraft/+bug/2033882
When listing parts in the after keyword of a part, if the listed part doesn't exist, no error will show.
In core20 it was showing an error but not in core22.
I believe it should show an error to help developers with potential typos.
### To Reproduce
The first build runs fine. The second build properly fails.
### part yaml
```shell
name: my-snap-name
base: core22
version: '0.1'
summary: Single-line elevator pitch
description: |
This is my-snap's description.
grade: devel
confinement: devmode
parts:
my-part:
plugin: nil
override-build: |
echo "hello"
my-part2:
after: [trololo]
plugin: nil
override-build: |
echo "hello"
```
### Relevant log output
```shell
While the same example in core20 always gives:
Failed to get part information: Cannot find the definition for part 'trololo', required by part 'my-part2'.
Remote parts are not supported with bases, so make sure that this part is defined in the `snapcraft.yaml`.
```
