 == Reproduction Report

 === Steps to Test
 Starting from WordPress 6.3:
 1. In `php.ini`, disable `disk_free_space()` by adding the line:
 `disable_functions = disk_free_space`.
 2. Restart the web server.
 3. Navigate to Site Health, and expand the disk space security notice.
 Observe the message.
 4. Upgrade to WordPress 6.3.1, then repeat Step 3.

 === Environment
 - Hardware: MacBook Pro Apple M1 Pro
 - OS: macOS 13.5.1
 - Server: nginx/1.25.2
 - PHP: 8.2.9
 - WordPress: 6.3, 6.3.1, and 6.3.2-alpha-56487

 === Actual Results
 - ❌ Before and after the 6.3->6.3.1 upgrade the notice indicates: "Could
 not determine available disk space for updates." Unable to reproduce.
