ref: Remove usage of aggregate-error library

[AbhiPrasad]

ref https://github.com/semantic-release/semantic-release/discussions/3376 ref https://github.com/es-tooling/module-replacements/issues/80

As per the package.json engines of this package, @semantic-release/github supports Node.js >=20.8.1.

As per https://github.com/sindresorhus/aggregate-error

Note: With Node.js 15, there's now a built-in AggregateError type.

This means we can remove the usage of this package and use the JavaScript built-in AggregateError.

I agree @AbhiPrasad 👍

Kindly address the following to get the PR ready for review 😉

• Tests failing in CI: Due to lint issues, kindly run the command npm run lint:prettier:fix on your dev branch... then run the tests again see whether it passes.
