v5.27.0-beta.1

• Signal Desktop now natively supports Apple's M1 chip which is used in their newer computers. If you're on one of those new-fangled devices, the app should be much snappier. If you're not, give a warm welcome to the users that are. Huge thanks to @dennisameling for his hard work here!
• On a long call? Your system should stay awake the whole time, instead of falling asleep while you're in the middle of an important discussion.
• There are also a number of small tweaks and bug fixes to keep Signal running smoothly, including several calling-related improvements.
