fix(deps): Bump @actions/core to 3.0.1 and @actions/github to 9.1.1 in internal GH actions

@actions/core 1.10.1 and @actions/github 5 pull in @actions/http-client 2, which depends on undici 5.29.0. There is no patched undici 5.x, so this moves the internal actions to the current majors. The actions are already ESM, and the APIs they use are unchanged. Dependabot alert: https://github.com/getsentry/sentry-javascript/security/dependabot/3393
