Replace NodeJS "path" with "upath": normalize paths to posix style

[slorber]

💥 Proposal

https://www.npmjs.com/package/upath#why

It could be less painful to ensure Windows support if all paths where using posix style (/ separator) instead of being platform dependent.

Windows/NodeJS is able to understand both / and \\ so it would be nice to normalize on all paths on posix style.

This could prevent issues we often see after committing, when the CI (build or tests) fails but only on Windows, such as:

My idea would be to:

• Use "upath" everywhere
• Use upath.normalize() everywhere instead of our custom posixPath() fn.
• Prevent "path" from being imported with an ESLint rule

Looks like @armano2 you mentioned path.posix instead of upath and deleted that comment?

Both can be a solution, but apparently, they do not have the exact same behavior: anodynos/upath#26

that's why i deleted my comment :)

Not sure we need upath, we don't often get windows path issues anymore after the problem has been understood
