[arch-events] CfP extension for FrOSCon DevRoom

Due to the corresponding number of requests I've received, I've decided to extend the deadline for the CfP submission for the Arch DevRoom at this year's FroSCOn another *two weeks*. You will find all the details at https://monochromec.com/Arch_DevRoom_CfP.html. Thanks, Chris -- This email account is monitored seven days a week.
