gimbalabs: build test via plutus-starter

[aleeusgr]

think there exists V2 version of
https://gitlab.com/gimbalabs/plutus-pbl-summer-2022/plutus-always-succeeds

Therefore I should add plutus-always-succeds and see if it works.
its tag is specified to be v2022-04-06

to test:

nix-shell$ cd /always-succeeds

# this may take a while the first time
cabal update
cabal repl 

Prelude MyFirstPlutusCompiler>

Right()

cabal: Could not resolve dependencies:
[__0] trying: plutus-starter-0.1.0.0 (user goal)
[__1] unknown package: serialize (dependency of plutus-starter)
[__1] fail (backjumping, conflict set: plutus-starter, serialize)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: plutus-starter, serialize

error: attribute 'shellFor' missing

its serialise

Hm, there could be an alternative; does plutus-apps not have examples of v2 contracts?

find the map and change the hash;

Is there any tooling to do that?
