fix(php-shim): keep literal '>' outside tags in strip_tags

The b'>' match arm in strip_tags's state machine never pushed the
character to the output buffer when encountered outside a tag (state
0), unlike every other special-character arm (!, ?, -, and the
catch-all) which does push in that state. Every literal '>' not part
of an HTML-like tag was silently dropped.

This corrupted "=>" into "=" in Composer's operation trace strings
(e.g. "Upgrading foo/bar (1.0.0 => 1.1.0)"), which go through
strip_tags to remove the <info>/<comment> markup before comparison,
un-ignoring 82 integration tests that were asserting on that exact
arrow.
