Update cs fixer to 3.94 and amend rule for phpdoc_line_span

PHP CS Fixer 3.94+ defaults class and enum case PHPDoc to multi-line when those keys are omitted. Our rules already force single-line property, method, and const docblocks; set class and case to null so those docblocks are not rewritten and upgrades do not churn unrelated files.

Fix deprecations of rulesets

The rule sets have been renamed so updating to use the new ruleset names.

This fixes:

Detected deprecations in use (they will stop working in next major release):

• Rule set "@PHP80Migration:risky" is deprecated. Use "@PHP8x0Migration:risky" instead.
• Rule set "@PHP82Migration" is deprecated. Use "@PHP8x2Migration" instead.
• Rule set "@PHPUnit100Migration:risky" is deprecated. Use "@PHPUnit10x0Migration:risky" instead.

Always import class names

This release enables the fully_qualified_strict_types ref to always require importing class names instead of backlashes.
