fix: use lastIndexOf to make getSamplePath cross-platform

On GitHub-hosted runners the workspace path contains the repo name
multiple times (e.g. .../igniteui-angular-examples/igniteui-angular-examples/...),
causing split(repoName)[1] to return "/" instead of the samples
sub-path. Downstream helpers (getSampleGroup, getSampleControl,
getSampleFolder) would then return undefined and crash utils.replace
with "Cannot read properties of undefined (reading 'split')".

Replace split(repoName)[1] with lastIndexOf + substring so the
function always anchors to the last occurrence of the repo name,
making it work correctly on Windows, macOS, and Linux regardless of
how many parent directories share the repo name.
