feat: add coraza_add_get_args to expose tx.AddGetRequestArgument

[potats0]

in libcoraza, we can't add http args. Now we only add http args by ProcessURI. But in ProcessURI func docs, it says that This function won't add GET arguments, they must be added with AddArgument.

therefore, I opened a PR to expose AddGetRequestArgument.

sorry I couldn't add unit test.because libcoraza is another repo and couldn't access the corazawaf transaction.variables. I couldn't access the variable of transaction in libcoraza unless use reflection.

There is a way to access Coraza transaction Variables, try:

txi := tx.(plugintypes.TransactionState)
argsGet := txi.Variables().ArgsGet()
