fix: update otel version to match Kong Gateway version

[hanshuebner]

Summary

To make this fix work, we're adding a hack that prevents the normal plugin compatibility checks to be done for the opentelemetry plugin if the version of the plugin reported by the DP is 0.1.0.

Tested using https://github.com/Kong/otel-hybrid-mode-hack-test

Cherry-pick to kong-ee is not needed as the problem does not exist there, the plugin's version is already in sync with Kong Gateway itself.

Can you also test whether green/blue upgrades still work? The change really only does something in mixed version hybrid mode situations.

@hanshuebner I ran our Plugin CP<>DP Version Compatibility tests with CP (including this fix) and DP (3.7.1) and these tests also passed for the OTEL plugin, no configuration issues were noticed https://github.com/Kong/kong-test-automation/actions/runs/9767950727/job/26964387736#step:7:184
