Let the Gradle wrapper retry its distribution download

CI died on 'Attempt 1/1 failed: Unexpected end of file from server' while
fetching the distribution zip. The wrapper was configured with retries=0, so a
single dropped connection failed the job, and a 10s timeout is tight for a
130 MB download behind a redirect.

Three retries with a 1s backoff, and a 60s timeout.
