[plugin-legacy] The default value of the modernTargets does not support all target browsers

[Fitz6]

Describe the bug

The default value of modernTargets is edge >= 80, firefox >= 72, chrome >= 80, safari >= 13.1, chromeAndroid >= 80, iOS >= 13.1.

For example, if my .browserslistrc is chrome > 63, then I used Promise.allSettled (available in Chrome >= 76).
Following the build process, if you attempt to open it in Chrome versions 64 to 79, you will encounter the error Uncaught TypeError: Promise.allSettled is not a function, as polyfills are not generated for these versions.

You must manually set modernTargets to chrome > 63 for it to work properly. It's confusing.
