feat: Update contrib for the experimental response propagator interface

[jerrytfleung]

Changes

• Applied Globals::responsePropagator() API in each HTTP instrumentation library
• Registered response propagators (servertiming, traceresponse) to the Registry
• Bumped API, SDK, Context version for each HTTP instrumentation library and Response Propagators in order to use the experimental response propagator API
• Fixed the GHA issue (e.g. style issue from Symfony, semconv issue from MongDB) so that all GHA(s) are passing.

Test result with Slim instrumentation

GHA is failing due to the assumption that open-telemetry/opentelemetry-php#1712 is in the main branch.

As open-telemetry/opentelemetry-php#1712 is merged, all the GHA(s) are passing now.

@open-telemetry/php-maintainers Please take a look. This PR is to apply the newly added experimental response propagator API to contrib.
