fix: normalize backslash in getStaticPaths() for windows (#53876)

styfle · web-flow · commit 6f7ffadc8608 · 2023-08-10T21:27:02.000Z
This normalizes the backslash for windows users who accidentally use `\` in the request paths instead of the expected `/`. For example, in nodejs/nodejs.org#5617 the slash was hardcoded for split that caused the backlash to remain the the `getStaticPaths()` result. - Fixes #51225
