fix: graalvm checksum for linux-aarch64

Checksums taken during apple#876 ended up out of date
due to the release of GraalVM `21.1.2` (the PR was
built against `21.1.1`).

These checksums are calculated from the GraalVM
download page directly:

https://www.graalvm.org/downloads/

On Linux:
```
sha256sum graalvm-...
```
