It is 2.8.2, not 2.7.3.

npm v9 is not compatible with Node 12, so we can't update to it yet.

Build tracing using CLIs before 2.7.3 no longer works with the most
recent update to the `ubuntu-22.04` runner image.

With this new logic, we can remove the workarounds around testing
`windows-2019` and `windows-2022`.

Previously the quoted values weren't visible in the PR description.

This change bumps a bunch of the internal actions packages. Note that
the only required version change is `actions/core` to 1.10.0. The others
are not required, but seem like a reasonable idea.

It also changes all of the workflows that use `set-output`.

* Clarify merging with merge commit

* Add merge commit message to mergeback PRs

Avoid requiring test-setup-python-scripts checks.

* Only test Java for CLI v2.5+

* Improve bash code style

* Set Actions error messages

python-setup: Fix venv creation in Ubuntu 22.04

This test is broken, as it first sets environment variables, and then
immediately unsets it again.
This only worked by chance with the legacy tracer, and breaks the Lua
tracer.
