Description of your pull request and other information

Closes #2041. reason() in util/pip_install.py only matched lines that start with ERROR: . When pip fails a wheel build it indents that line ( ERROR: Failed building wheel for cryptography), so the annotation fell back to "pip failed without an ERROR line".

• reason() now strips each line's indent before matching and still takes the last match. Pip's closing Failed to build … and error: failed-wheel-build-for-install lines carry no ERROR: prefix and say less.
• On run 39718608950's pypy3.10 log, the annotation now reads Failed building wheel for cryptography. The rest of this leg is skipped.
• New tests use a fixture copied from that log, plus tab-indented, last-match and empty-ERROR: cases. A second test pins the deliberate departure from the old inline shell, which had the same gap.

The new tests fail without the fix (3 failed, 18 passed) and pass with it (19 passed). With test_python_matrix_tiers_1633: 45 passed. experimental.yml's inline copy of the old sed has the same gap; #2032 replaces it with this script.

GOOD TO GO at 1db0f1057 (Sonnet cross-review). Fed the real pypy3.10 log (job 119628835034), reason() returns Failed building wheel for cryptography. The match is still case-sensitive, so the nested build's error:/Error: lines don't match, and %/, escaping still happens downstream. The "departs on purpose" test runs only on its own fixture, so every other parity case is unchanged.
