fix(import): handle EEXIST when importing OpenAPI collections with paths grouping (#7499)

Use { recursive: true } in mkdirSync during collection import so that
directories which already exist (e.g. due to duplicate or case-colliding
path params like {customerID} vs {customerId}) do not throw EEXIST and
abort the import.
