There are 43 instances of posix shell tests and 35 instances of bash. To
give us a single consistent language for testing in, replace
all #!/bin/sh to #!/bin/bash. Common sources that are included in both
different shells will now work as expected. And we no longer have to fix
up bashisms that appear to work when someone's system has sh symlinked
to bash, but don't work on other systems that have both shells
installed.
Although we could have chosen sh, it's not backwards compatible so it
wouldn't be possible to bulk convert without re-writing the existing
bash tests.
Choosing bash also gives us some nicer features including 'local'
variable definitions and regexes in if statements that are already
widely used in the tests.
It's not expected that there are any users with only sh available due to
the large number of bash tests that exist.
Discussed in relation to running shellcheck here:

Python's json.tool will output the input json to stdout. Redirect to
/dev/null to avoid blocking on stdout writes.

Write the JSON output to a specific file to avoid debug output
breaking it.
