Closes #2

Strip the deprecated License :: OSI Approved :: Apache Software License trove classifier from all 77 contrib pyproject.toml files (incl. _template) — the SPDX license = "Apache-2.0" field is retained, so no metadata is lost. Brings contrib into parity with core (Linear OSS-30, Q1). Q6/Q7 required no change / deferred (see comments); Q3/Q4 noted as follow-up.

Validation: scope contained to pyproject.toml files + changelog; grep for the classifier returns 0; all changed TOML parse-validated; all retain the SPDX license field.

Title: Remove deprecated OSI Approved license trove classifier

What

Removes the deprecated License :: OSI Approved :: Apache Software License trove classifier from all 77 package pyproject.toml files that declared it, including the package _template and the workflow-generator lib.

Why

Every affected file already declares license = "Apache-2.0" (SPDX), so the trove classifier is redundant. Per PEP 639 the license trove classifiers are deprecated in favor of the SPDX license expression, and packaging tooling warns when both are present. Core opentelemetry-python has already dropped the classifier everywhere; this brings contrib into alignment.

Scope

Only the single classifier line is removed from each file; no other metadata is touched. _template/pyproject.toml is included so new packages generated from the template don't reintroduce the classifier. No behavioral or dependency changes.

Verification

• grep -rl "License :: OSI Approved" --include=pyproject.toml . returns no results.
• All modified pyproject.toml files parse successfully with tomllib.
• All modified files retain license = "Apache-2.0".
