Add Ruby 3.3/3.4/4.0, drop EOL 2.7

- Drop Ruby 2.7 (EOL; fabrication 2.31 already requires >= 3.0)
- Add Ruby 3.3, 3.4, 4.0 to CI matrix
- Bump required_ruby_version to >= 3.0 in all four gemspecs
- Update .ruby-version to 3.4

Ruby 3.4 changed Hash#inspect to use the new hash syntax for
symbol keys: {regex: /foo/} instead of {:regex=>/foo/}. The
validation error message includes hash params via #inspect, so
the spec regex needs to match both formats for compatibility
across Ruby versions.
