Describe the bug

Forge install uses absolute path in git submodule configuration.
This is will fail github action because git couldn't find submodule by lib/openzeppelin-contracts

[submodule "/home/jack/Dev/InfinityToken/lib/openzeppelin-contracts"]
	path = /home/jack/Dev/InfinityToken/lib/openzeppelin-contracts
	url = https://github.com/OpenZeppelin/openzeppelin-contracts

I have to change it to

[submodule "lib/openzeppelin-contracts"]
	path = lib/openzeppelin-contracts
	url = https://github.com/OpenZeppelin/openzeppelin-contracts
