fix: unused variable warning in support_package.rs

[joshrotenberg]

Issue

Windows build shows unused variable warning:

warning: unused variable: `metadata`
   --> crates\redisctl\src\commands\enterprise\support_package.rs:399:15
    |
399 |     if let Ok(metadata) = fs::metadata(parent_dir) {
    |               ^^^^^^^^ help: if this is intentional, prefix it with an underscore: `_metadata`

Fix

Prefix with underscore if intentional:

if let Ok(_metadata) = fs::metadata(parent_dir) {

Or remove the binding entirely if not needed:

if fs::metadata(parent_dir).is_ok() {
