apps-config: drop the foreign chains' type bundles

typesBundle carried overrides for 140 chains inherited from upstream;
none of them is a Pezkuwi chain. The live Pezkuwi and Zagros runtimes
(pezkuwichain, asset-hub-pezkuwichain, people-pezkuwichain, zagros and
its asset hub, bridge hub, collectives, coretime and people) match no
entry and need none: they carry metadata v14+.

The spec files, the Cere chain bundle, the custom derives and the 32
npm packages they came from are removed, among them GPL-3.0-only ones
(pontem, moonbeam, subsocial, jamton) that were bundled into this
Apache-2.0 app. The spec/chain/derives mechanism stays, empty, for a
chain that ever needs one. typesBundle.ts is regenerated (15 lines).
yarn.lock loses 3250 lines, elliptic and the old @polkadot/api trees
with them.
