Update Pallet Preimage weights

[ahmadkaouk]

What does it do?

New weights for pallet preimage generated with the following command

./target/production/moonbeam benchmark pallet --chain=moonbase-dev --steps=50 --repeat=20 --pallet=pallet_preimage --extrinsic=* --header=./file_header.txt --output=./runtime/common/src/weights/

What important points reviewers should know?

Is there something left for follow-up PRs?

What alternative implementations were considered?

Are there relevant PRs or issues in other repositories (Substrate, Polkadot, Frontier, Cumulus)?

What value does it bring to the blockchain users?
