This adds the MySQL 26.10 innovation release to the relevant GitHub Actions test matrices.

When MySQL 9.7 (an LTS release) was added in r62407 / 4e28109, the innovation release handling was removed because there was no newer innovation release to test. This restores that handling for 26.10:

  • PHPUnit (phpunit-tests.yml): MySQL 26.10 is added back to the test-innovation-releases job, along with the mariadb/26.10 exclusion. MySQL 9.7 remains in the LTS jobs.
  • Upgrade testing (upgrade-testing.yml): 26.10 is added alongside 9.7 for the recent releases and oldest supported WordPress version jobs, as the methodology in the file describes (all LTS versions plus the most recent innovation release).
  • Install and local Docker environment testing: 26.10 and 26.7 are added to the 7-2 entry in .version-support-mysql.json, which both workflows use to build their matrices. 26.7 is added to the "Only test the latest innovation release" exclusions in both workflows, so only 26.10 runs. install-testing.yml also excludes 26.10 with PHP 7.2 and 7.3 (MySQL 9.0+ does not work with them, see #61218). This matches what already exists for 9.7.

The LTS defaults are unchanged. .env.example still uses 9.7, and the trimmed routine PHPUnit matrix and limited fork matrix still test 9.7.

This adds the MySQL 26.10 innovation release to the relevant testing strategies.

Because MySQL 9.7 is an LTS release, some of the innovation release handling was removed when it was added in r62407. This restores that handling for 26.10.

MySQL 26.7 is added to the supported versions list but excluded from the install and local Docker environment test matrices, as only the most recent innovation release is tested.
