The advisory states that the regression was introduced in 37.0.0 and that prior releases are unaffected. Align the PyPI range with the existing Rust range so wasmtime-bin 36.x is not flagged.

Problem
GHSA-vvp9-h8p2-xwfcstates that the regression was introduced in Wasmtime37.0.0and that36.0.xand all prior versions are unaffected. The Rust package range starts at37.0.0, but the PyPIwasmtime-binrange starts at0. Because PyPI publisheswasmtime-bin36.0.9, the current range marks an explicitly unaffected release as vulnerable.Change
wasmtime-binaffected range at37.0.0.37.0.2fixed boundary, Rust package range, and all other advisory metadata unchanged.Evidence
