[BUG] LNURLw not following lnurl withdraw specs

[michaelWuensch]

Describe the bug
When you create a LNURLw voucher that has a higher amount than available in the wallet and you try to withdraw it, the response is malformed. Wallets cannot read the error message if it doesn't follow the spec.

The specs can be found here:
https://github.com/lnurl/luds/blob/luds/03.md
The relevant section is step 6.

To Reproduce
Steps to reproduce the behavior:

1. Create a wallet and fund it with 100 sats
2. Enable LNURLw
3. Create a voucher with 150 sats
4. Try to withdraw it with a wallet

Expected behavior
This response is expected:
{"status": "ERROR", "reason": "Withdraw not working. Insufficient balance"}

But this response is delivered:
{"detail":"withdraw not working. Insufficient balance."}

Desktop (please complete the following information):

• LNbits version: 0.10.10, Commit version: 3260acbcc7e907fa9c9c60d0582bf974031f917b
• tested on https://legend.lnbits.com

Additional context
Wallets cannot read this error message if it doesn't follow the spec.

Awesome!
I tried it on the demo server ( https://legend.lnbits.com )
I just checked it and it is still v0.1.1 there. As I am not an admin I cannot change it.
