Closes #4

Incrementally widen contrib pyright strict scope (Linear OSS-31, Q2): add opentelemetry-distro to the pyright include (needed only a trivial _configure(self, **kwargs: object) -> None annotation), plus the tox typecheck dep so pyright resolves it. pyright stays green (0 errors). Q5 (coverage-in-CI) deferred with justification (auto-generated workflows + maintainer Codecov token); no plumbing removed. Remaining packages listed for follow-up.

Validation: scope contained to pyproject + tox.ini + distro src + changelog; pyright 0 errors / 0 warnings on the expanded set.

Title: Add opentelemetry-distro to the pyright strict type-checking scope

What

Extends the pyright strict include by one package (opentelemetry-distro), as part of the incremental widening the config comment already calls for ("Add progressively instrumentation packages here.").

Scope

• Annotate OpenTelemetryDistro._configure as (self, **kwargs: object) -> None (the only strict finding in the package).
• Add opentelemetry-distro to [tool.pyright] include.
• Add {toxinidir}/opentelemetry-distro to the typecheck tox env so pyright can resolve the local package.

Why

pyright runs in strict mode but only covers a minority of packages; unlisted packages are effectively unchecked. This raises the typed floor by one more package while keeping CI green.

Verification

Ran the repo's pyright command (via the typecheck env dependency set) with the package added: 0 errors, 0 warnings, 0 informations.

Remaining work

Most packages still aren't type-checked and need more annotation work before they can be added cleanly (a few are close: resource-detector-containerid, resourcedetector-gcp at ~2 errors each; many others range from a couple dozen to a few hundred strict errors). Those are intentionally left for separate, focused PRs to keep this change small and reviewable.
