feat: bump polkadot versions to v0.9.37

[trusch]

fixes KILTProtocol/ticket#2392

Breaking Changes for us

None! 🥳

Edit: Forgot to also check with try-runtime feature enabled. There is a small tweak necessary because of This PR about on-runtime-upgrade

No database migrations, no runtime migrations and no new host functions.

Cool new stuff that might be useful (or not)

• frame_support::storage: Add StorageStreamIter
  • If we have a StorageValue that contains something iterable, we can directly iterate over it, without copying the memory first by a regular get() call.
• Add ensure_* mathematical methods
  • The checked_* family of calls returns an Option which is in 99% of the cases mapped to an error
  • ensure_* calls directly return an error which can be propagated using questionmark operator more easily
• Kusama shows how to express complex local origins in XCM messages
  • Perhaps the most interesting one in this release, would be a good idea for @weichweich and @ntn-x2 to have a look into this
• pallet_uniques successor NFTv2 is out! 🥳 😄
  • Finally we can have NFTs with owner controlled metadata on our chain.
  • They even literally mention that this way users can write DIDs directly on their NFT!

How to test:

Please provide a brief step-by-step instruction.
If necessary provide information about dependencies (specific configuration, branches, database dumps, etc.)

• Step 1
• Step 2
• etc.

Checklist:

• I have verified that the code works
  • No panics! (checked arithmetic ops, no indexing array[3] use get(3), ...)
• I have verified that the code is easy to understand
  • If not, I have left a well-balanced amount of inline comments
• I have left the code in a better state
• I have documented the changes (where applicable)

Great! Would be nice (for the future) to also link the Polkadot release so that we can easily click and check ourselves, if something comes up 🙂
