@joystream/types: Rename AccountInfo, make dependencies exact, add types required by new node

[Lezek123]

Updated @joystream/types following the AccountInfo type rename in the runtime (to StorageProviderAccountInfo): e01eb1c

The reason this rename was introduced is because the AccountInfo type name was colliding with one the new Substrate core types (see: https://github.com/polkadot-js/api/blob/master/packages/types/src/interfaces/system/types.ts).

I also fixed yarn.lock which seemed outdated on the current iznik branch and was causing some dependency issues.

Since the yarn.lock fix wasn't enough, because the issue was still present during npm pack CI check, I changed @polkadot dependencies to exact versions to prevent incompatible versions like 1.28.1 from beeing installed.

FYI: I suggested a better name for the renamed AccountInfo #1148 (comment)

Added types required by the node after fb9845b

  Address: 'AccountId',
  LookupSource: 'AccountId',

Confirmed that this solves the issue with extrinsics discussed in #1126

Changed the name from StorageProviderAccountInfo to ServiceProviderRecord because of expected rename in the runtime.
