Respect sdk-path-prefix when checking page paths

pageExists now slices links with a hard-coded "/sdk/typescript/" prefix, so the checker ignores the configured sdk-path-prefix input. In any workflow that sets a different prefix (for example the /docs/api case documented in this action’s README), valid sidebar links resolve to incorrect file paths and are reported as missing_page. This regresses the action’s advertised ability to run against other repo layouts.
