report versions of the used tools

[staabm]

Describe the feature
would be great the build-output would show which version of the tools are used.

I guess we are currently running in one of the bugs the recent composer releases had, but were fixed in the subsequent release (we had 2 or 3 releases yesterday).

since I cannot see which version of composer the build is using I cannot confirm my thesis easily.

Version
using the latest v2 tag

@staabm By default it will always setup the latest release version.

I had not done this as some tools have a startup time and checking the version adds to the CI runtime. I will run some tests again.
Currently, I would recommend adding a step after setup-php step to check the tool version.
For cs2pr it will be 1.3.0 release. It shows the versions as 1.1.1-dev though as it picks $version in the script.

- name: Check versions
  run: |
    composer -V
    cs2pr version

Thx for the headsup. Just created a cs2pr issue staabm/annotate-pull-request-from-checkstyle#51
