* Add pythnet migration files

Also:
- Add related env vars for testnet networks. Mainnet ones to be added
when it's ready.
- Rename Pyth2Wormhole env vars to solana

* Add mainnet emitter

* Fix migration file numbers

* Address Jayant comments

* pyth2wormhole: add rent adjustment to the initialize() instruction

* pyth2wormhole migrate(): Leave a note about rent adjustment

The migrate() ix won't be called in the nearest future - it does not
make sense to bloat the program bytecode with the rent adjustment. The
note describes the what and why in detail.

This changeset adjusts p2w_autoattest.py commitment to confirmed and
fixes a get_transaction() failure that happened due to the upstream
default finalized commitment setting (RpcClient's set value is not
used). This is fixed by using the chosen commitment explicitly via
get_transaction_with_config()

* Fix migration files
