Code Review

This pull request updates the README.md file to center-align the Kokkos logo and add logos for the High Performance Software Foundation (HPSF) and the Linux Foundation. The reviewer identified that some of the newly added image URLs point to GitHub blob HTML pages instead of raw image files, which will prevent them from rendering correctly, and provided suggestions to append ?raw=true to resolve this issue.
