[fix]Continuous optionals should not throw conflict error

[aolose]

fix issue 7925

folder structure [[a]]/[[b]]/+page will throw routes conflict error

the error from the function prevent_conflicts

here:

permutations = [
...permutations.map((x) => x + next),
...permutations.map((x) => x + `<${matcher}>${next}`)
];

will generate permutations [ '//', '/<>/', '//<>', '/<>/<>' ]
but actually, it' impossible match route /empty/[[b]] . so '//<*>' should be remove from result.

Thank you! Could you add a changeset and add a test in the index.spec.js file next to the changed file?

okay, done.

thanks for the test, however for this it's sufficient to create a unit test - you would create another unit test similar to the existing one in create_manifest_data/index.spec.js at line 718.
