Follows up on #60194, which fixed the encoding in temporaryUploadUrl but missed the identical pattern in temporaryUrl introduced by #60137.

Background

#60137 added rawurlencode($path) to both temporaryUrl and temporaryUploadUrl so reserved URI characters (?, &, #) in storage keys couldn't escape the path segment of a signed URL.

rawurlencode also encodes / as %2F, so nested storage keys produced URLs that no longer matched the storage serve/upload routes. #60194 fixed this in temporaryUploadUrl with strtr(rawurlencode($path), ['%2F' => '/']), but the sibling call site two methods up in temporaryUrl was left with the bare rawurlencode($path).

Reproduction

$url = Storage::temporaryUrl('nested/folder/photo.jpg', now()->addMinute());
// http://localhost/storage/.../nested%2Ffolder%2Fphoto.jpg?expires=...&signature=...

A GET against that URL hits the storage serve route with an encoded key the route can't resolve, so users see a 404 / 403 instead of the file.

PHPUnit output before the fix:

Failed asserting that 'http://localhost/storage/nested%2Ffolder%2Fserve-file-test.txt?expires=...&signature=...'
contains "nested/folder/serve-file-test.txt".

Fix

Mirror #60194 — apply the same strtr decode step in temporaryUrl so ?, &, # stay escaped while / is preserved.

After

$url = Storage::temporaryUrl('nested/folder/photo.jpg', now()->addMinute());
// http://localhost/storage/.../nested/folder/photo.jpg?expires=...&signature=...
