I updated blog post after reading comments from Matrix/Slack/Phoronix/HN/Lobster/etc. places.

- mentioned which board had 143 minutes, added info about time on Milk-V Megrez board

- added section 'what we need hw-wise for being in fedora'

- added link to my desktop post to point that it is aarch64, not x86-64

- wording around qemu to show that I use it locally only
