Version `next` for package `@docusaurus/core` could not be found

🐛 Bug Report

Hello there,

When i used to use 2.0.0-alpha.66, Everything was good. But, when i have upgraded to 2.0.0-alpha.68 manually, then this issue started. This issue didn't effect my project. But, IDK this will give me a major issue or not but as a perfectionist 🤣 i would like to run my app without any errors. And this continues to 2.0.0-alpha.69 too. I though this will get a fix on next update but didn't. So I would like to raise an issue. Please do close and if this is a duplication, cause I couldn't able to find any issue similar to this.

To Reproduce

manually change version from2.0.0-alpha.66 to 2.0.0-alpha.66+

"dependencies": {

"@docusaurus/preset-classic": "^2.0.0-alpha.69",
//…//
}

Remove node_modules folder and run npm i
Run the project F5(VSCode). terminal looks obsoletely fine. But, not the debug console. Here is that looks like(I'm pointing the issue)
