[gis_web] Correct pub.dev changelog entry. (#5613)

The previous push to this package didn't update its pub.dev score/docs [(error log)](https://pub.dev/packages/google_identity_services_web/versions/0.3.0/score/log.txt).

---

This PR attempts to re-publish the package, in the hope that it was a transient error in pub.

~~Maybe workaround for https://github.com/dart-lang/pub-dev/issues/7267~~

It's confirmed that this was a transient error in pub, this PR now just corrects the changelog of the previous change to list the correct dart/flutter versions that are required (and update the dependency definitions to match the rest of the repo)
