Logging outputs "key" rather than the key

[fletc3her]

In MockDataStoreUtils.luau on line 73 the output uses "key" rather than the variable key.

Current output:
08:52:19.511 [GlobalDataStore] [CuServerData/CuServerData] [GetAsync] key - Server - MockDataStoreUtils:76

Expected output:
08:52:19.511 [GlobalDataStore] [CuServerData/CuServerData] [GetAsync] tst_1772729374_imp - Server - MockDataStoreUtils:76
