cli: proposal to add complete 'allVersions' metadata

[vince-fugnitto]

Description

The proposal is to add the more complete allVersions information when performing:

$ ovsx get <extension> --metadata

At the moment, the command will return allVersions in the form of:

"allVersions": {
        "latest": "https://open-vsx.org/api/vscode/yaml/latest",
        "preview": "https://open-vsx.org/api/vscode/yaml/preview",
        "1.56.0-next.e95ce0a810b": "https://open-vsx.org/api/vscode/yaml/1.56.0-next.e95ce0a810b",
        "1.56.0-next.9e9ad5b905f": "https://open-vsx.org/api/vscode/yaml/1.56.0-next.9e9ad5b905f",
        "1.56.0-next.08d37a85a3f": "https://open-vsx.org/api/vscode/yaml/1.56.0-next.08d37a85a3f",
        "1.56.0-next.4853ea69eb4": "https://open-vsx.org/api/vscode/yaml/1.56.0-next.4853ea69eb4",

Would it be possible to provide the complete information similarly to what getSearch provides?

"allVersions": [
        {
          "url": "https://open-vsx.org/api/vscode/yaml/1.56.0-next.e95ce0a810b",
          "files": {
            "download": "https://open-vsx.org/api/vscode/yaml/1.56.0-next.e95ce0a810b/file/vscode.yaml-1.56.0-next.e95ce0a810b.vsix"
          },
          "version": "1.56.0-next.e95ce0a810b",
          "engines": {
            "vscode": "*"
          }
        },

It would provide additional information, and allow for additional use-case (downloading compatible extensions through cli). Please let me know if its not the correct approach or desired.
