[flashrom] flashrom discord channel

[Anastasia Klimchuk]

Hello everyone,

I wanted to share that there is a #flashrom channel on discord. It
existed for a while, but I only very recently learned about it. I
suspect it might be the same for many people who have no idea the
channel exists.

I updated the Contacts page (old and new) with the info: see
https://www.flashrom.org/Contact#Discord
or check the latest doc/contact.rst in your repo,
and follow the invite link.

The channel is on the coreboot server, so if you join you get all of
coreboot and flashrom channels in one place, which is convenient.

See you there,
