Sync spells-mainnet with spells-goerli

[The-Arbiter]

During PE-1098, Julien made some changes in config.sol for the goerli spell which I did not replicate in the mainnet spell. This PR will fix these discrepancies as well as other issues.

This PR brings the diffchecker diffs in config.sol down from 150+ to 10.

Changes to config.sol:

• Comments around the difference in pause_delay value for spell system values
• Changing mainnet collateral values to match Julien's basis points style expression (i.e. 40_00 instead of 4000) and removal of the seconds keyword
• Changing clip_tip for TUSD-A to 0 on Goerli (currently 500). Note that the tip value on Goerli is actually 500 whereas on mainnet it is 0, so this will cause failure of this test for the spell immediately after this PR is merged on Goerli.
• Changing individually commented lines (//) to block comments (/* */) to allow for use of DiffChecker when maintaining these files.
• Addition of CRVV1ETHSTETH-A (commented out) to Goerli's config.sol
• Addition of INST-WETH-A and INST-WBTC-A (both commented out) to Mainnet's config.sol

Closing this as it's no longer relevant since Goerli deprecation.
