Noticed some mistakes in the xml samples

I’ve noticed some mistakes in the xml samples. Here are some examples:

Standard_Credit_Note.xml:
After decoding the Qr barcode the invoice hash was [gFn1TDoinkSt9x2zyJwQsfFodrnNrjCK3g/o6NevEmM=] even though in the invoice itself the hash is [xMrSevWwYISRPsWiUO59wpirUrKPhluH7GMsasKB3RQ=]

Standard_Invoice:
The invoice hash is incorrect [20+7kdZgFAtIBs6vlOThRd/i8EXnKFO6pNfl+4o/dzk=] the correct one should be [V4U5qlZ3yXQ/Si1AC/R8SLc3F+iNy27wdVe8IWRqFAQ=] but even in the qr the invoice hash is different from these 2 [f+0WCqnPkInI+eL9G3LAry12fTPf+toC9UX07F4fI+s=]

There are some other mistakes too in other samples. I think these samples should be updated in the upcoming release.

@Busaeed thank you very much for highlighting these mistakes. These are well received and ZATCA teams will ensure to correct the mistakes in XML sample in the coming release of SDK.
