Fix NPM packages name validation (#26595)

- Added new tests to cover corner cases
- Replace existing regex with new one
Closes #26551 

---
As @silverwind suggested, I started from
[validate-npm-package-name](https://github.com/npm/validate-npm-package-name),
but found this solution too complicated.
Then I tried to fix existing regex myself, but thought, that exclude all
restricted symbols is harder, than set only allowed symbols.
Then I search a bit more and found
[package-name-regex](https://github.com/dword-design/package-name-regex)
and regex from it works for all new test cases.

Let me know, if more information or help with this PR is needed.
