Moves named catalog deps to unnamed

[scamden]

make a dep with a named catalog
some package
"graphql": "catalog:graphql15",

with

catalogs:
  graphql15:
    graphql: ^15.3.0

run pnpx codemod pnpm/catalog

becomes

"graphql": "catalog:",

expected: should leave the named catalog

(Seems like this only reproduces if the named catalog comes after the default one in pnpm-worspace.yaml)

(It's also notable that I had one package referencing graphql not in a catalog and one referencing the named one)
