Describe the bug

Caret incorrectly added (report)

Running yarn dlx storybook@8.0.0-alpha.14 upgrade puts Storybook dependencies into the package.json with a caret, although it should be listed without.

Caret incorrectly omitted (report)

After installation, exact version numbers are added to the package.json instead of versions with a caret specifier.

Doubled version number (report)

If you then run npx storybook@next add @storybook/addon-themes@8.0.0-alpha.14, it will try to install @storybook/addon-themes@8.0.0-alpha.14@^8.0.0-alpha.14. (first, it probably shouldn't use the caret, second there's the parsing issue)
