Makes the 14 data providers in tests/phpunit/tests/secrets/ static. PHPUnit 10 deprecates data providers that are not public and static, and PHPUnit 11 removes support for them.

None of these providers use $this, so only the static keyword is added. Seven files change, with one word per provider.

Trac ticket: https://core.trac.wordpress.org/ticket/66211

Testing Instructions

Run each changed file, on single site and multisite:

npm run test:php -- tests/phpunit/tests/secrets/

All tests pass. The skipped tests in wpSecretsConfigKeyProvider.php and wpSecretsKeyManager.php depend on the environment, and are skipped the same way on trunk.
