fix(semver): stop classical pattern matching 6+ digit versions

The regex crate parses PCRE's possessive \d{1,5}+ as a stacked
repetition (?:\d{1,5})+, i.e. \d+, so date versions like 20121020
matched the classical pattern and normalized to 20121020.0.0.0 instead
of falling through to the date(time) pattern like PHP. The plain
\d{1,5} is equivalent to the possessive form here per the
regex-porting rules. Un-ignore test_find_recommended_require_version
which this had blocked.
