This script was already present in the directory
tools/ansible/roles/tbb-nightly-build/files, however this directory will
soon be removed as part of #40196.

Versions bump and Changelog update

The previous dummy addresses of form 0.0.X.0 were marked by Tor as
internal, causing bandwidth events to be skipped. This changes
pluggable transport dummy addresses to the 192.0.2.0/24 range.

Versions bump and Changelog update

Grammar lesson by arma.

We save logs of the sign-nightly script by redirecting STDOUT and STDERR
to a file. However, when the output is not a terminal, STDOUT will have
buffering by default, but STDERR will not, which results in some lines
being written in the wrong order in our log file. To avoid that we
enable autoflush on STDOUT.

When fetching the dependencies for Fenix for some reason an older
GeckoView version gets downloaded: the one used immediately before the
final bump for android-components 70.0.0.

I am not sure which .pom file is the culprit but this breaks our builds
when using our android-components 70.0.0 which requires the GeckoView
dependency it got actually tagged with.
