This adds a new command to package.json `verify` which can be run via
`pnpm verify`.
The command runs the certora CLI with a config file which has to be
adjusted for every individual project.
The commit also adds a dedicated task to our github actions, which
ensures, verification is done in every PR as well.
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.
