Make it easier for people to find information we need for a bug report,
and show it on AboutActivity.
New info is:
- Device manufacturer (e.g., "Google") and model (e.g., "Pixel 4a (5G)")
- Android version (e.g., "13")
- SDK version (e.g., "33")
- Active account (e.g., "@Tusky@mastodon.social")
- Server's version (e.g., "4.1.2+nightly-20230627")
All info is copyable to make it easy to include in a bug report. A
button to copy the information is also shown.
