Make insta CLI work outside of cargo, and distribute it via npm

[untitaker]

sentry uses insta to review snapshot files generated by python code. There is an ad-hoc implementation of insta-the-library vendored somewhere in sentry.utils.pytest.fixtures.

People who want to review those snapshots currently have to install insta via cargo. What if insta used cargo-dist to distribute insta CLI on npm instead? Then sentry can add it to the developer's setup using yarn add --dev. Yes, as a frontend dev dependency, but everybody knows how to install those. Better would be pypi package, but who has time for that.

Another option would be to make it self installable like rye does from github releases maybe?

fwiw i tried cargo-dist on another project and it isn't really hard to get it working for both npm + prebuilt binaries, can recommend

cargo-insta now has binaries. Closing this as resolved.
