Proto: Migrate from Mumbai

Reference MR for Lima: !6504 (merged)

---

Context

1. Remove references to Lima and replace them with Mumbai within the protocol

2. Update the constants representation by copying from the Proto Mumbai

   Also:

   • Remove code related to block time reduction
   • Use constants from previous protocol if available

3. Update Tezt tests to migrate from Mumbai

4. Update Python tests to migrate from Mumbai

Manual testing

Import a recent rolling node snapshot.

wget https://mainnet-v15.xtz-shots.io/mainnet-3066445.rolling
./octez-node snapshot import mainnet-3066445.rolling --block BLjV4aKB4vzKALmtrKEuBYCuoBUkJNZJ1ojm6NqXNoNTwwF9snc

Patch the files for yes wallet/node.

dune exec devtools/yes_wallet/yes_wallet.exe -- create from context ~/.tezos-node in /tmp/yes-wallet --active-bakers-only
patch -p1 < scripts/yes-node.patch

Patch the node configutation such that it upgrades the protocol.

Run the following in on terminal to start the node.

./octez-node run --synchronisation-threshold 0 --connections 0 --rpc-addr localhost

Run this in another terminal to bake the block migrating to Mumbai:

./octez-client -d /tmp/yes-wallet bake for --minimal-timestamp

You should see something like this in the node logs to show Mumbai activation:

Run this to bake the block migrating to Alpha:

You should see something like this in the node logs to show Alpha activation:
