In a recent build [with an unusually long change message?] this failed, due to the overall limit on environment variable size in Linux:
```
An error occurred trying to start process '/usr/bin/bash' with working directory '/home/runner/work/Adafruit_CircuitPython_Bundle/Adafruit_CircuitPython_Bundle'. Argument list too long
```

[link will work for a limited time due to github actions log expiration
policy]
The new printed value may not be 100% the same as the old one but it's
real close.
build.yml failed because `echo "$GITHUB_CONTEXT" caused an `argument list too long` error.
Try printing GITHUB_CONTEXT with `printenv` instead, to avoid this.
This causes build failures, because these are usually the "automated
update by adabot", and when the workflow runs the new release has
been created but the metadata is not yet available.
Instead, rely on the cron coming a few hours after adabot so that
the metadata is created & ready.
Typical failure:
