Bump the grpc-go fork to pick up the cherry-picked fix for CVE-2026-33186 (CVSS 9.1), which enforces strict path checking for incoming requests on the server, preventing authorization bypass via malformed :path headers. Signed-off-by: Daniel Mellado <dmellado@fedoraproject.org>

Changes
Bump the
thanos-community/grpc-gofork to pick up the cherry-picked fix forCVE-2026-33186 (CVSS 9.1) from thanos-community/grpc-go#1.
This enforces strict path checking for incoming requests on the server,
rejecting any request with a non-canonical
:pathheader (missing the leadingslash) with an
Unimplementederror. Without this fix, malformed paths couldbypass path-based restricted "deny" rules in interceptors like
grpc/authz.Verification
Dependency-only change (
go.mod/go.sum). The fix itself is tested upstreamin grpc/grpc-go#8985.
