The template benchmark doesn't work.

[Lohann]

The pallet-template benchmark weights depends on substrate's frame-weight-template.hbs which doesn't exists in this repo.

the following command doesn't work:

./target/release/solochain-template-node benchmark pallet \
  --chain=dev \
  --pallet=pallet_template \
  --extrinsic='*' \
  --steps=50 \
  --repeat=20 \
  --wasm-execution=compiled \
  --output=pallets/template/src/weights.rs \
  --template ../../.maintain/frame-weight-template.hbs

fails with:

Input("Handlebars template file could not be found: \"../../.maintain/frame-weight-template.hbs\"")

I understand the goal of this repo is being a template that doesn't require clone the whole polkadot-sdk repo, so IMO it must be self contained and include the frame-weight-template.hbs file.
