Add codeSubstitutes to rococo parachains

[skunert]

Since the fix for #4559 was to add a codeSubstitute to the rococo-parachains, we should update the chain-specs in the repo.

The json diffs are not super easy to review, so if you want to manually check:

• Run for example jd -o people-rococo.diff people-rococo-from-this-branch.json people-rococo-master.json
• Check in the resulting diff file that only codeSubstitutes field is changed

I've checked that the following code substitutes were added:

asset-hub-rococo.json:
@ ["codeSubstitutes","4960799"]

bridge-hub-rococo.json:
@ ["codeSubstitutes","3603599"]

contracts-rococo.json:
@ ["codeSubstitutes","5359899"]

coretime-rococo.json:
@ ["codeSubstitutes","1627199"]

people-rococo.json:
@ ["codeSubstitutes","1209599"]

Can we do any better in reviewing of these changes?

So basically to do the full verification your can build the runtimes for the chains in question.
I used this commit: d3bf1a8
Then build the runtimes, we are interested in the .compact.compressed ones.

cargo build --release -p people-rococo-runtime -p contracts-rococo-runtime -p bridge-hub-rococo-runtime -p asset-hub-rococo-runtime -p coretime-rococo-runtime`, then the runtime wasm files are located in `target/release/wbuild

These files should be the same as the bytes that were substituted in the chain-specs here.

As far as the block numbers go, you should be able to see a big gap in time after these blocks in pjs. But yeah, otherwise not much to do. You can in addition verify that they are the same ones as in #4600 , which are the ones that are now live on rococo and proven to be working.

What version of toolchain is required? So far I get runtimes of different sizes)

This is not reproducible. You would need to use a reproducible env like srtool. Generally, these are test networks and I think we can trust @skunert enough to have compiled the correct code ;)
