Update PHP images and add PHP 8.5 support

[mikelittle]

Summary

Refresh the PHP image map in class-docker-compose-generator.php to pick up the latest patch releases from humanmade/docker-wordpress-php, and add PHP 8.5:

• 8.5 → humanmade/altis-local-server-php:8.5.3 (new)
• 8.4 → 8.4.4 → 8.4.9
• 8.3 → 8.3.23 → 8.3.24
• 8.2 → 8.2.36 → 8.2.37
• 8.1 unchanged (6.0.30)

Test plan

• composer server start succeeds on each of php: "8.5", "8.4", "8.3", "8.2"
• composer server cli -- wp eval 'echo PHP_VERSION;' reports the expected major.minor for each

I'm wondering why this isn't backported to v26, v25, v24? Do we only support specific PHP version per Altis version?

We don't support php 8.5 in the older branches, this next release will be the first.
Hence, three different PR for three different sets of supported php versions.
