MySQL 8.2 removed expire_logs_days, but the Drupal 6–10 MySQL 8 configs still set it, so mysql:8.2, 8.3 and 8.4 abort on startup with unknown variable 'expire_logs_days=10'. The bare mysql:8 alias (MySQL 8.4.5) was also loading the 5.7 config file and failing on query_cache_limit.

• Replace expire_logs_days = 10 with binlog_expire_logs_seconds = 864000: same 10 days, supported since MySQL 8.0.1
• Send mysql:8 to the MySQL 8 config
• Compare the pinned image version when deciding whether to force mysql_native_password, so mysql:8 (8.4) no longer gets an auth setting MySQL 8.4 rejects. 8.0–8.3 behave as before
• Drupal 11's config was already fixed in Improve MySQL 8.4 Support #159 and is untouched
• Add examples/drupal10-mysql84 on mysql:8 to CI

Verified locally on Lando 3.26.9: lando start with database: mysql:8 boots MySQL 8.4.5 with the MySQL 8 config and binlog_expire_logs_seconds=864000. The new example passes in Leia.

Fixes #186

Note

Medium Risk
Changes default MySQL config files and authentication defaults for the mysql:8 alias across Drupal recipes; mis-versioning could still break local database boots.

Overview
Fixes Drupal recipe MySQL 8.2+ and mysql:8 startup failures by aligning configs and version handling with current MySQL images.

All Drupal 6–10 mysql8.cnf templates now set binlog_expire_logs_seconds = 864000 instead of the removed expire_logs_days, so MySQL 8.2+ no longer aborts on unknown variables. Default config selection treats any 8.x database tag (including mysql:8) as MySQL 8 and loads mysql8.cnf instead of the 5.7 file. The drupal-mysql builder resolves pinned image versions before choosing mysql_native_password, so mysql:8 (8.4) is not forced onto auth settings 8.4 rejects while 8.0–8.3 behavior stays the same.

CI adds examples/drupal10-mysql84 to the Leia matrix and pins lando/run-leia-action to 1.0.0-beta.4; the unreleased changelog documents the fixes (Fixes #186).
