Use mysql version from server rather than mysql --version

[grooverdan]

mysql --version is the version of the client program and not necessarly the server version.

Get the version accurate for the reports generated.

LGTM but not tested!

Sample output:

    "php_version": "7.4.33",
    "php_modules": {
        "bcmath": false,
        "curl": "7.4.33",
        "filter": "7.4.33",

}

Needs one more change however - putting file_put_contents( __DIR__ . '/tests/phpunit/build/logs/env.json' after fetching the the mysql version. I'll append this soon.

Was appened so the generated file env.json is:

cat env.json 
{
    "php_version": "8.2.10",
    "php_modules": {
        "bcmath": false,
        "curl": "8.2.10",
        "dom": "20031129",
        "exif": false,
        "filter": "8.2.10",
        "gd": "8.2.10",
        "gettext": false,
        "gmagick": false,
        "iconv": "8.2.10",
        "imagick": false,
        "intl": false,
        "libsodium": false,
        "libxml": "8.2.10",
        "mbstring": "8.2.10",

    },
    "os_name": "Linux",
    "os_version": "6.4.12-200.fc38.x86_64",
    "mysql_version": "11.2.2-MariaDB-1:11.2.2+maria~ubu2204"
}

This is a combined version with #177 like master...grooverdan:phpunit-test-runner:all_changes.
