refactor(@angular/ssr): update getPathSegments to use stripTrailingSlash instead of filter(Boolean)

This change modifies the `getPathSegments` function to use `stripTrailingSlash`, providing a more consistent and reliable way to handle trailing slashes in paths. This update also resolves issues causing CI failures.

(cherry picked from commit b0c2d19)
