Motivation

Add hardhat-secure-accounts support to GRE.

Changes

Account management methods (getDeployer, getTestAccounts and getNamedAccounts) are now hooked up to hardhat-secure-accounts plugin by default. This can be disabled using the flag disableSecureAccounts, see GRE readme for more details.

Example:

// Without secure accounts
> const graph = hre.graph({ disableSecureAccounts: true })
> const deployer = await g.l1.getDeployer()
> deployer.address
'0xBc7f4d3a85B820fDB1058FD93073Eb6bc9AAF59b'


// With secure accounts
> const graph = hre.graph()
> const deployer = await g.l1.getDeployer()
== Using secure accounts, please unlock an account for L1(goerli)
Available accounts:  goerli-deployer, arbitrum-goerli-deployer, rinkeby-deployer, test-mnemonic
Choose an account to unlock (use tab to autocomplete): test-mnemonic
Enter the password for this account: ************
> deployer.address
'0x90F8bf6A479f320ead074411a4B0e7944Ea8c9C1'

Note Shuffled the code a bit which makes this seem like a bigger change than it is. Renamed helpers/network.ts --> helpers/chain.ts and also added an unrelated helpers/network.ts which makes GitHub diff viewer to go wild.

Fixed the error!

About the documentation reference, the GRE README.md mentions the plugin and links to it already, do you think we should add more?
