[Bug][SubscriptionBilling] OnAfterInitFromSubscriptionLine in "Vend. Sub. Contract Line"

[stephanweidmann]

Describe the issue

I want to syncronize CustSubContractLine with VendSubContractLine and add the "OnAfterInitFromSubscriptionLine"- Publisher in the VendSubContractLine. This would improve the extensibility.
I did not found any open issue or pullrequest where this publisher in "VendSubContract Line" has already been requested.

Expected behavior

-> Extend the assignment of vend. Sub Contract line with infos from the subscription line
This is done in "InitFromServiceCommitment" in "Vend. Sub Contract line"

In "Cust. Sub. Contract Line", there is a OnAfterInitFromubscriptionLine-Publisher, that is not available in purchase.

Steps to reproduce

https://github.com/microsoft/BCApps/blob/main/src/Apps/W1/Subscription%20Billing/App/Vendor%20Contracts/Tables/VendSubContractLine.Table.al

Goto Line 505

Compare with https://github.com/microsoft/BCApps/blob/main/src/Apps/W1/Subscription%20Billing/App/Customer%20Contracts/Tables/CustSubContractLine.Table.al

GoTo Line 463

Additional context

If someone who already set up the repository and knows the whole process can provide this event, I would be happy.
If not, i would try to fix it (as in "I will integrate the publisher"

I will provide a fix for a bug
