Closes #331.

The base litestar extra now requires litestar 2.22, up from 2.19. Before, only litestar-otl needed 2.22, for litestar.plugins.opentelemetry. With the floor raised, that module is always there, so the split and its probe go:

• pyproject.toml: the base comment gains the 2.22 reason, and litestar-otl loses its own litestar>=2.22 line and comment.
• import_checker.is_litestar_opentelemetry_installed no longer probes litestar.plugins.opentelemetry. That was one of the dotted find_spec calls that import litestar when lite_bootstrap is imported (Import bootstrappers lazily from lite_bootstrap/__init__.py #308).
• The Litestar OpenTelemetry instrument's skip message is now "opentelemetry-instrumentation-asgi is not installed".

Tests

No new test. Nothing behaves differently at the new floor, as the issue says.

One correction to the issue: a test did assert the old message. test_litestar_otel_is_skipped_without_litestars_opentelemetry_plugin hid litestar.plugins.opentelemetry and expected a warning matching litestar>=2.22. It covered only the probe this deletes, so it is deleted too. The missing-asgi case is still covered by test_import_checker_survives_incomplete_opentelemetry_namespace.

The full suite passes, 556 tests at 100% coverage (just test-ci). just lint (including ty), just adr-check and just docs-build pass too.

I ran the floors job's steps locally for the litestar target on 3.11, 3.12, 3.13 and 3.14. CI excludes 3.15 for this target. All four resolve litestar 2.22.0 and pass scripts/floor_smoke.py. No other target installs litestar.

Breaking changes
