test(autotest): drop verify: on basic-editing save-all-step5

Last remaining CI failure (run 25665240373): the save-all-step5 verify
text 'All files saved, no compilation errors' caused an LLM downgrade.

After the prior step 'apply-code-action Create method call()' Eclipse
inserts a TODO-marked stub. The LLM consistently flagged the lingering
TODO marker as 'compilation error persists', concluding Save All didn't
work. Ground truth: verifyProblems.errors:0 already passes (TODOs are
not errors).

Drop verify: text — deterministic verifier remains.

Local: java-basic-editing 21/21 with LLM verification on.
