LIBVER does not reflect the correct version in google/apiclient 2.18.2

LIBVER does not reflect the correct version in google/apiclient 2.18.2

The LIBVER constant in google/apiclient does not update correctly when a new version is released.
Currently, in google/apiclient version 2.18.2, the LIBVER constant still shows "2.12.6", which causes confusion regarding the actual installed version.

Steps to Reproduce

1. Install google/apiclient using Composer:

composer require google/apiclient

2. Check the installed version:

composer show google/apiclient

Expected output (for example):

google/apiclient 2.18.2

3. Run the following PHP script:

use Google\Client;
echo Client::LIBVER;

Actual output:

2.12.6

Even though the installed version is 2.18.2, LIBVER does not reflect the correct version.
Expected Behavior

The LIBVER constant in src/Client.php should be updated to reflect the actual package version in each new release.
Environment

    google/apiclient: 2.18.2
    PHP Version: 8.2.12
    Laravel Version: 11.44.1

Suggested Fix

Update the LIBVER constant in src/Client.php whenever a new version is released.

Thank you for your work on this library! 🚀

Ahh yes, we keep forgetting about that constant.

I've submitted #2672 to update it, and to add a check to verify it. What we really should do is modify the release-please updater to handle it, but this will suffice for now.
