lldbgdbremote.md: Update qWasmLocal result description

The current description mistakenly specified that an address of the local value in some address space is returned. When testing this with Wasm runtimes that already implement this command, it can be clearly seen that the value is returned. The value itself may be an address for languages that use shadow stack in Wasm linear memory, but the value of an arbitrary local does not always contain that address.
