Remove PHP opentelemetry extension to re-enable JIT on 8.5

[loks0n]

Summary

• Remove the opentelemetry PECL extension from the default image. Its observer hooks override zend_execute_ex, which causes opcache to refuse to enable JIT on PHP 8.5.
• Drop the opentelemetry build stage, version env, COPY, and docker-php-ext-enable entry from the Dockerfile.
• Drop the opentelemetry assertion from tests.yaml.
• Add a 1.2.2 entry to CHANGES.md.

Test plan

• docker build --no-cache --tag appwrite/base:latest . succeeds
• container-structure-test test --config tests.yaml --image appwrite/base:latest passes
• docker run appwrite/base:latest php -m no longer lists opentelemetry
• With opcache.jit=tracing + opcache.jit_buffer_size>0, php --ri opcache reports JIT enabled (no "JIT is incompatible with third party extensions that override zend_execute_ex" warning)

Greptile Summary

This PR removes the opentelemetry PECL extension from the base image to restore opcache JIT compatibility on PHP 8.5. The removal is consistent across all four touch points — ENV version pin, build stage, COPY instruction, and docker-php-ext-enable — and the test assertion and changelog are updated accordingly.

Confidence Score: 5/5

Safe to merge; the removal is complete and consistent across Dockerfile, tests, and changelog.

All references to opentelemetry are correctly removed with no leftover artifacts, the test suite is updated in lockstep, and the version bump is appropriate for a potentially breaking removal.

No files require special attention.
