Apache #NuttX RTOS: Analysing the Most Expensive PR

We did a Quantitative Analysis of our Most Expensive PR (in terms of GitHub Runner Usage), here's what we found: (1) We really need to fix the downloading of Build Dependencies (2) We should disable the Build Config for `bl602evb/elf` (3) Later we should show our developers how to build and test PRs in our own repos. - Next Video: https://youtu.be/LBhEJ6Qf4iM - Previous Video: https://youtu.be/SoBq9nGcpM4 - Spreadsheet for Most Expensive PR: https://docs.google.com/spreadsheets/d/1HY7fIZzd_fs3QPyA0TX7vsYOjL86m1fNOf1Wls93luI/edit?gid=961366697#gid=961366697 - Spreadsheet for NuttX GitHub Jobs: https://docs.google.com/spreadsheets/d/1HY7fIZzd_fs3QPyA0TX7vsYOjL86m1fNOf1Wls93luI/edit?gid=1187577522#gid=1187577522 - Script to dump PRs and Jobs from GitHub: https://github.com/lupyuen/nuttx-github-jobs - NuttX Issue: https://github.com/apache/nuttx/issues/17914
