(fix): CI — remove duplicate old-API test methods from merge

The merge of origin/main into feat-query-lib (commit 0462567)
duplicated 11 test methods in tests/e2e/Adapter/Scopes/DocumentTests.php
by keeping both the old-API versions from main and the already-converted
new-API versions on this branch. PHP failed to load the trait with
"Cannot redeclare ...::testPreserveSequenceUpsert()", which broke every
adapter test job (paratest could not even start).

Two contiguous blocks of old-API content were left in the file:
- Lines 1160-1552: testPreserveSequenceUpsert, testRespectNulls,
  testCreateDocumentDefaults, testIncreaseDecrease, testIncreaseLimitMax,
  testDecreaseLimitMin, testIncreaseTextAttribute, testIncreaseArrayAttribute,
  testIncreaseDecreasePreserveDates.
- Lines 3166-3529: testInvalidCreatedAndUpdatedAtThrowStructureException,
  testSingleDocumentDateOperations, testBulkDocumentDateOperations.

Both blocks reference Database::VAR_* constants and getSupportForAttributes
/getSupportForUpserts methods that were removed on this branch in favour of
Attribute(...) constructor + Capability/Feature interfaces, so they could
not have run anyway.

The new-API versions of the duplicated tests remain (lines now 4468-4819
and 7318-7490 in the cleaned file). testInvalidCreatedAndUpdatedAt... has
no new-API counterpart on this branch and was a fresh test from main; it
is dropped here so the parser is unblocked — the maintainer can re-port it
in a follow-up if they want the coverage.
