fix(path): export private types used in public API

[jsejcksn]

The ParsedPath type is used as the return type for the function parse, which is part of the public API… yet it is only exported from the "private" module _interface.ts. Item number 4 in the Recommended Usage states this…

Do not import modules with a directory or filename prefixed by an underscore (they're not intended for public use).

…which means that it's currently impossible to import the type in a recommended way. This PR re-exports the type from the parse modules which use it so that the parse function and the ParsedPath type can now be imported together:

import { parse, type ParsedPath } from "@std/path/parse";
