[5.3.0][FIX] Prevent crash when funds warning is pressed

[tommasini]

Description
The app is crashing when we do not have enough funds to do a transaction on testnet

Proposed Solution
The app will redirect to the MetaMask faucet when it's testnet
The app will redirect to onRamp with the crypto we are trying to transact

Code Impact
Medium, was changed in all transaction confirmations screens/modals:

• Confirm screen of send flow
• Modal of transaction Review
• Modal of transaction approval

Test Cases
(For mainnet, avax and rinkeby)
Case 1:

• Press the warning on the confirm screen of send flow
  Case 2:
• Press the warning on transaction modal of deeplinks
  Case 3:
• Press the warning on transaction modal of webview

Some custom networks have the ability to onramp. for example BSC, Polygon, Avalanche.
With that being said if i were to be on any of those custom networks (in my case i was on polygon) & i tap the warning message I am taken the faucet page

To reproduce:

• with an account with no funds add a custom network (for example BSC, Polygon, Avalanche.)
• go to https://metamask.github.io/test-dapp/
• connect your wallet
• tap on deploy contract, or create token
• now tap on the warning message
• notice the error

• Replaced all the places where transaction needs to be confirmed
• The message is according to the coin that you are trying to transact
• New coins added, BSC, Polygon, Avalanche, Celo and Fantom

@tommasini The app no longer crashes but we have an issue. The custom networks (BSC, Polygon, Avalanche, Celo and Fantom) were hard coded into the networks list: http://recordit.co/NfLmFZAph1

This should not be the case. Only mainnet & testnets should be hard coded in the network lists.

To reproduce:
launch the app
create/import your wallet
on the wallet view tap on the network name in the top nav.
notice (BSC, Polygon, Avalanche, Celo and Fantom) is automatically added.

Furthermore If I were to select any of the hard coded networks I get Error: Unrecognized network type: 'polygon'
