What this changes

The weekly upstream watch's L4T check has not run for at least this month. NVIDIA removed the directory listing at https://repo.download.nvidia.com/jetson/common/dists/, so it returns 404. The script printed "couldn't reach NVIDIA's apt repo (HTTP Error 404: Not Found): L4T not checked this run" and passed. The Oct 12 run (38258673077) shows it.

• The check now reads https://repo.download.nvidia.com/jetson/, which lists every package file, and takes the L4T versions from the t234 nvidia-l4t-core packages (nvidia-l4t-core_36.5.2-...deb).
• It compares full versions against L4T_VERSION=36.5.2, so a point release like 36.5.3 is reported. Before, it compared only 36.5.
• A 404 or an index with no t234 nvidia-l4t-core entries now fails the run, since both mean the URL or format changed again. Timeouts and other network errors still skip the check for that run.

Checks

• Called report_l4t() against the live index: it reports nothing new for 36.5.2. With the pin set to 36.4.7 it reports r36.5.0, r36.5.1, r36.5.2.
• scripts/ci/lint.sh is clean.
• The workflow itself was not run, since it edits issues on whatever repo it runs in.

Noticed, not fixed

• The index page is about 3 MB. That is one download a week.

@allengregoryiv new one, ready for a review. The weekly upstream watch's L4T check has been skipping since NVIDIA removed the directory listing it read. Details are in the description.
