fix: use path.normalize to convert POSIX paths to OS-specific paths

[haines]

Closes: #5322

(from #5324): The build currently breaks when loading routes

ENOENT: no such file or directory, open '<root>/app/outes/<route file>'

Note it is trying to load from outes not routes!

The bug was introduced in #5266. By splitting and rejoining the paths, it drops the leading / on Unix-like systems, converting /Users/me/... to Users/me/.... However appDirectory still has a leading / so removing directory prefixes with slice drops one too many characters.

This PR resolves the issue by using path.normalize to covert / to \ on Windows, rather than splitting and rejoining the paths.

Hey @haines, could you target the dev branch instead ? 🙏🏼

[haines]

@machour done! Could you please re-approve the workflow run?

[sockthedev]

TIL 👍

[machour]

As far as I see, this PR is modifying a test already passing.
Could you revert that and add a new test case to verify what you're fixing instead? 🤔

[haines]

@machour the existing test just mirrors the production code, so the test has the same bug and it needs to be modified. The problem is that the test exercises the internal function flatRoutesUniversal (to avoid having to run against a real filesystem), but the bug occurs in flatRoutes.

I could rewrite the test to exercise flatRoutes instead, but that'd require writing the test files to the filesystem (in a temporary directory). What do you think?
