Subject: [PATCH] fix(commonjs): handle global shorthand property correctly

When `global` is used as a shorthand property in an object literal (e.g.,
`{global}`), the plugin was replacing `global` with
`commonjsHelpers.commonjsGlobal`, resulting in invalid syntax
`{commonjsHelpers.commonjsGlobal}`.

This fix follows the same pattern used for the `require` shorthand case:
when detecting a shorthand property, prepend `global: ` to convert it to a
full property before replacing the value.

Fixes rollup/rollup#6242
