test: remove duplicate test in explicit_push_trigger codemod

[github-actions]

Test Suite Reduction: src/compile/codemods/0006_explicit_push_trigger.rs

What was wrong

• injects_all_branches_push_when_on_absent_in_old_source was a duplicate of fires_for_the_release_immediately_before_the_cutover: both use the same effective context (compiler_version: INTRODUCED_IN / 0.48.0, source_compiler_version: Some("0.48.0") — old_ctx() resolves to exactly this), the same input ("name: x\ndescription: y\n"), and the same assertions (apply_codemod returns true, push_include equals ["*"]). The second test provides strictly more documentation value (doc comment explaining the release-window boundary), so it was kept.

Changes

Test	Action	Reason
injects_all_branches_push_when_on_absent_in_old_source	Removed	Exact duplicate of fires_for_the_release_immediately_before_the_cutover

Verification

• cargo test: all 3179 tests pass ✅ (one fewer than before, matching the removed duplicate)
• cargo clippy --all-targets --all-features: no warnings ✅
