[NA] [CI] chore: set version to 0.1.0 for first public release (#22)

pyproject was at 0.1.1 (bumped only to avoid a TestPyPI upload collision during
testing). The first PUBLIC PyPI release is 0.1.0, and the draft GitHub release is
tagged v0.1.0 — the publish workflow's guard requires tag == pyproject version,
so set it back to 0.1.0. PyPI has never seen opik-hermes, so no collision.
