Subject: [PATCH] test: make transformProjectRoot CWD-agnostic

Fix issue where tests fail when run from directories like /node
because the project root path appears as a substring in URLs
(nodejs.org) or other paths (/node_modules).

Use a regex that only matches the project root when followed by
a path separator, colon, whitespace, or end of string.

Fixes: https://github.com/nodejs/node/issues/61303
