What was changed?

Following guidance from issue 390 with a couple of additional changes to support project column in output.

• api: images_all_projects :

• new API extension to both internal/version/api.go and doc/api-extensions.md

• incusd/images: Add support for all_projects:

• Add support for all-projects to cmd/incusd/images.go for the imagesGet function.

• Include adding the all-projects to the swagger comments on imagesGet.

• Also, add Project field to Image struct and update value in GetImageByFingerprintPrefix in shared/api/image.go and internal/server/db/images.go respectively

• doc/rest-api: Refresh swagger YAML

• Re-generate the swagger YAML data

• client: Add GetImagesAllProjects

• Add a new GetImagesAllProjects function to client/incus_images.go and add that function to the ImageServer interface in client/interfaces.go

• Implement it in client/simplestreams_images.go as an alias for the standard GetImages.

• incus/image: Add --all-projects flag to list

• Add the new argument to cmd/incus/image.go, when passed, call GetImagesAllProjects instead of GetImages.

• Also, add shorthad char e(for Project) and print project name when passed

• i18n: Update translation templates

• Re-generate the translation template for the new CLI string.

Looks good, just suggested a small edit to make it slightly clearer what API endpoint is touched and what's added.

As we're going to want the pull request to include all the commits for this new feature, I'm going to mark the pull request as draft for now. Feel free to add the commits to this one as you get them ready and I'll keep an eye and review as they show up.
