Subject: [PATCH 1/2] GH Actions: add builds against Composer 2.2 for PHP 7.2 -
 8.x

Composer 2.3 drops support for PHP < 7.2, so for PHP 5.4 to 7.1, `v2` will install Composer 2.2, for PHP 7.2 and up, `v2` will install Composer 2.3.
These extra builds make sure the Composer 2.2 LTS version will continue to be 100% supported for PHP 7.2-8.x.

Subject: [PATCH 2/2] Test bootstrap: tweak the version determination regex

Apparently, Composer 2.3.0 dropped the word `version` from the `--version` output ;-)

Output on Composer 2.2 and lower:
```
Composer version 2.2.10 2022-03-29 21:55:35
```

Composer 2.3 output:
```
Composer 2.3.0 2022-03-30 11:15:36
```
