Steps for migrating each meeting page

1. Create new meeting page
2. Move over the meeting assets (slides)
3. Create yaml data files for different talks from (https://github.com/llvm/llvm-www/tree/main/devmtg/)
4. Test it locally if all the content is visible as on the old website (https://llvm.org/devmtg/2023-05/)
