This is an initial take on adjusting the foundry-template to the Vac's
smart contract unit's needs. In a nutshell what this does is:
1. Update README to not refer to upstream repo where not necessary
2. Removes PRBergTest library from dependencies
3. Removes `FUNDING.qml`
4. Adjust CI actions
There are more things to be done and decided on in follow-up commits.
