[BUG] npm view returning string without quotes with version 10.8.0

[byCedric]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

When using npm view <package> <selector> --json, I expect only to receive JSON data types. Unfortunately, for npm@10.8.0 that's not the case anymore.

Running npm view expo-template-bare-minimum@sdk-51 dist.tarball --json now yields the tarball string, without quotes, making it not a JSON result anymore.

Expected Behavior

When using this same command with npm@10.7.0, the response is wrapped in quotes, making it a valid JSON response (or at least parsable through JSON.parse(...).

Steps To Reproduce

Result that's not parsable with JSON.parse:

1. $ npm i -g npm@10.8.0
2. $ npm -v → Should return 10.8.0
3. $ npm view expo-template-bare-minimum@sdk-51 dist.tarball --json
   → Should return https://... (without quotes)

Result that is parsable with JSON.parse:

1. $ npm i -g npm@10.7.0
2. $ npm -v → Should return 10.7.0
3. $ npm view expo-template-bare-minimum@sdk-51 dist.tarball --json
   → Should return "https://..." (with quotes)

• npm: 10.8.0

I introduced this in #7513. Will have a PR to fix it shortly.
