Builtin istanbul coverage directly into Rstest is too heavy. Rstest can provide a separate package for users to install as needed. When users set provider: 'istanbul', rstest can import the relevant transform plugin and provider from @rstest/coverage-istanbul.

This path should be imported from @rstest/coverage-istanbul rather than hard-coded in rstset.
And target/wasm32-wasip1/release/swc_plugin_coverage.wasm is the default export of swc-plugin-coverage-instrument
