The methods are documented as such in FileSystem. If we don't do this, there will be a discrepancy between getFastDigest and stat, as the latter can follow symlinks. This can manifest as a crash (see #20246) as the digest computation will take the missing fast digest for a symlink as a signal to compute the digest manually; this would fail when the symlink target is an in-memory file, which doesn't have an associated inode as required to compute the cache key (see DigestUtils#manuallyComputeDigest).
Fixes #20246.
