`forge install` fails on fresh clone

[marcuspang]

Running forge install after cloning the repo doesn't work out of the box.

git submodule exited with code 128:
Submodule path 'lib/avalanche-interchain-token-transfer': checked out '3a06a32d7e3a9fb6bc78df39ce0447d8dfbc069d'
Submodule path 'lib/avalanche-interchain-token-transfer/contracts/lib/forge-std': checked out 'ae570fec082bfe1c1f45b0acca4a2b4f84d345ce'

I resolved this by checking out to main branch and running again.

cd lib/avalanche-interchain-token-transfer
git checkout main
